Free Work Space For Veterans At WeWork helps entreprenuership


By Erika Prafder

At Wework on 57th Street Brett D'Alessandro (left) and Alexa Modero (right) run Backpacks for Life. 

Upon his return from deployment in Afghanistan as a sergeant in the Marines, Brett D’Alessandro had a tough time re-integrating.
“I went through hell, as a lot of vets do,” he says.
With medical help and that of organizations such as the Starlight Military Program, Veteran Racing Team and Operation Rebound, D’Alessandro recovered, but on the way to an appointment, he spotted a homeless vet.
“I went to my motel and pulled together a backpack filled with hats, gloves and warm clothing layers, and brought it to him,” he says.
Days later, “I saw him with a little boy, his son, who thanked me for the pack and said he didn’t have to go to school with books in hand. I thought about other vets suffering out there. There are so many resources, but a big disconnect between vets navigating them and finding them,” says D’Alessandro.
Inspired to help, he and his girlfriend, Alexa Modero, created Backpacks for Life, a 501c3 nonprofit organization that collects toiletries and basic supplies in backpacks and distributes them to needy vets with the help of Stand Down events, veteran service organizations, first responders and police officers. They also coach and mentor homeless and at-risk veterans.
Since launching his nonprofit in 2014 and leaving the military in 2016, the charity has given out 5,500 packs. To create revenue, they have developed personalized packs equipped with a locking cable and reflective material.
Then, in August, they were accepted to the Veterans in Residence program at WeWork. This nationwide effort was launched in 2016 by the global network of workspaces and Bunker Labs, a nonprofit that helps vets and their families start and grow their businesses.
Through the partnership, WeWork builds specially designed quarters with dedicated lounges and meeting rooms, providing vets with six months of free access to workspaces, facilities and services of WeWork’s community, which is currently over 300,000 strong globally.
With their Bunker Labs affiliation, each local group meets weekly with a team leader to work on business plans and to support one another in growth efforts. Citywide networking events with other veteran entrepreneurs are also hosted. Today, there are about 150 Veterans in Residence across 14 US cities.
“We host about 60,000 events per year, including fireside chats with famous veteran chief marketing officers or CEOs,” says Padden Murphy, WeWork’s global head of policy and impact.

Since every entrepreneur’s journey is different, “we’re trying to leverage and activate member companies and members to help folks build a product, a team, help with product launches and form strategic partnerships. If you’re a Vet in Residence, your story is our story.”
If, after their six-month program, vets need more time, “we are experimenting with extending for another six months,” says Murphy. “Vets make amazing entrepreneurs and business owners. They have ideas to help their communities. The number of vet-owned businesses is impressive and large — about 9.1 percent here. About 5 million people are employed by them and their payroll is about $200 billion. They are a core part and natural drivers of our economy.”
Nancy Preston, an Army veteran and West Point graduate, can attest to that. After leaving the military in 2009, Preston worked in the corporate world for eight years before deciding to start Milk Money Kitchens Inc., a consulting and coaching firm for food entrepreneurs.
“Cooks just want to cook,” she says. “Many have no idea what their numbers are. I wanted to help them start and run their businesses, optimize efficiency and make them more profitable.”
Preston joined Veterans in Residence in August, and the benefits are invaluable.
“The relationships I’ve built with other companies and their networks expanded mine by five times. I’ve generated good leads. Through lunch-and-learns and happy hours, the program organizers have put me in front of real-estate investors and legal firms, helping me to structure my company better. There’s been measurable progress,” she says.
Another advantage is the legitimacy the workspace offers, says Preston.
“Before, I was conducting business meetings in restaurants and coffee shops. Being able to meet clients at any of WeWork’s offices has earned me new revenue.”
Veterans can apply for the program at WeWork.com.

Mental Illness: The Silent Destroyer

Entrepreneurship demands so much, it can be easy to lose ourselves as we chase success.

Mental Illness: The Silent Destroyer
GUEST WRITER
President of Katherine Keller International LLC
11 min read
Opinions expressed by Entrepreneur contributors are their own.
My world had collapsed around me. The mask I wore had been ripped off, exposing me for who I really was: a human, blemished, with a serial habit of making mistakes. The world now knew that I was imperfect, despite all my attempts to persuade everyone otherwise. This was no nightmare with hope of awakening. This was my life with real people, real terror and real humiliation.
I was terrified to leave my house. The ringing of the phone sent me into a panic attack. I declined invitations to go out because I simply was too mortified to speak to anyone. I could feel judgment all around me. I decided life was easier and much safer where I could lock doors and silence my notifications.
By all accounts, I was clinically depressed. I understand that now. Living in the moment, however, I believed those who lived with depression were victims of tragedies beyond their control. Life had done something to them. Me? I had no justification for being depressed. This was the bed I'd made, and I was determined to lie in it without complaint.
With intention and the right support, I realized the sources of my depression and got back to health. But strong feelings stir up now and again, and current events sometimes trigger vivid memories. I reflected on my journey earlier this month, when Jason Kander announced he was dropping out of the Kansas City mayoral race to focus on coping with his post-traumatic stress disorder (PTSD). Kander was thinking suicidal thoughts even as he propelled himself to the height of his career.  
“So many men and women who served our country did so much more than me and were in so much more danger than I was on my four-month tour," he said in his public statement. "I can’t have PTSD, I told myself, because I didn’t earn it.”
As entrepreneurs, we often make the mistake of thinking we can do it all -- and that we have to accomplish everything right now. These four false justifications aren't only unrealistic but also unhealthy and ultimately counterproductive to building sustainable success. Keep reading to learn how to reframe these arguments and discover helpful steps you can take toward real healing.

Justification 1: “I didn’t earn it.”

How many of us have suffered in silence, like Kander did for so long? We rationalize we haven't endured long enough to complain because others have it worse than we do. Or we blame ourselves because we've made mistakes and wrongly decide the entire situation is our own fault.
Growing up, I heard my parents give plenty of advice: “Walk it off” and “Suck it up, buttercup” were favorites in our household. Whining only would get us sent to our rooms. My parents had little empathy for the hurdles we faced, and conversation rarely focused on emotions. We skipped right ahead: "What is the next step?" and "How are we going to fix it?"
To be fair, this mental fortitude has served me well in life. I spend little time dwelling on setbacks or heartbreak. I swallow them like vile-tasting medication and move on. In fact, I attribute my successes to my ability to get up and “walk it off” each time I fall.
This grit, though, is inseparable from the “I-didn’t-earn-it” mentality: I haven’t earned the right to be sad, complain, suffer from depression or develop PTSD. That’s an unfortunate connection, as research from federal health agencies and nonprofit professional associations affirms that entrepreneurs are far more likely than other adults to live with mental illness. This holds true across diagnoses including depression, ADHD, substance abuse/addiction and bipolar disorder.  

Justification 2: “I should be happy.”

In the Netflix documentary "Avicii: True Stories," the title character -- a critically celebrated and commercially successful DJ -- shares his inner turmoil: "I looked at everyone around me, and they looked as if they were doing well. I felt crazy. I have everything I've always wanted, so I should be happy." Tim Bergling, whose stage name was an alternate spelling for the lowest realm of Buddhist hell, died by suicide in April 2018. He was 28.
In some of my own lowest moments, I lay in bed, staring at the ceiling to remind myself I had a roof over my head and food in the fridge.  I said the words aloud, over and over. I wish I could say it was some sort of gratitude incantation, but my eyes weren’t filled with tears from my overwhelming appreciation for life. The words were a sharp, prescriptive chastisement that I should be happy and grateful for all I had. Each time, though, I felt an increasing guilt and shame around my depression.  
The relationship between success and happiness is a complex one. In his TED Talk titled “The Happy Secret to Better Work,” author and former Harvard psychologist Shawn Anchor shared a few questions he’s asked repeatedly. “Shawn,” friends say, “why do you waste your time studying happiness at Harvard? What does a Harvard student possibly have to be unhappy about?”
Embedded within the larger life question, Anchor said, are the keys to understanding the underlying science of happiness: “Because what that question assumes is that our external world is predictive of our happiness levels, when in reality, if I know everything about your external world, I can only predict about 10 percent of your long-term happiness.”

Justification 3: “Mental struggles = weakness.”

Marketing and leadership training sessions toss around the word “authenticity” as a quality sought by customers, employees and people in general. In other words, “Cut out the BS and just be real!” At the same time, we all have at least one Facebook friend who shares details we didn’t need or want to know. When a person holds nothing back, we find ourselves wanting to say, “Time to dial down the authenticity.”
Impression management is the art of finding that balance between what you share and don’t share to thoughtfully present yourself to the world. Most entrepreneurs are hyper-aware to the fact their choice of dress, words and actions shape others’ opinions of them.
Humans don’t like to be exposed. We prefer to control what others can and cannot see, framing perceptions of our public selves. The stigmas surrounding mental health typically contrast starkly with the infallible strength we entrepreneurs want to project. Our innate response: Keep it hidden. We don’t ask for help because we fear how even a hint of uncertainty will negatively influence how others see us -- or potentially jeopardize our business futures.

Justification 4: “I will be happy when …”

Success is an ever-changing goalpost. My son is one of the most determined teenagers I’ve ever known. As a scrawny 12-year-old, he saw our high school’s Junior Reserve Officers’ Training Corps (JROTC) perform in an armed exhibition team competition. Of the nation’s more than 1,700 JROTC programs, ours consistently ranks in the Top 10. In that awe-filled moment, he decided success meant making that team.
Camps, bruises, workouts and stitches in his head all were part of the process. He earned his place during freshman year, but his definition of success already had changed. As a sophomore, he worked to achieve an undefeated season. He arrived first, left last and volunteered for every task. Now, he’s a junior -- and commander of the team that rendered him speechless just four years ago. This summer he sat wide-eyed as he watched the U.S. Army Armed Exhibition Team perform. And just as he did when he was 12, he decided that success meant making that team.
Success is just a moment. Yesterday’s triumph no longer is enough. But what if we believe happiness always lies on the other side of success?
  • I will be happy when I can afford an assistant to help me.
  • I will be happy when I earn a six-figure income.
  • I will be happy when I make a seven-figure income.
  • I will be happy when my company is bought out or goes public.
  • I will be happy when I retire.
The truth is we obtain success more easily when we decide first to be happy. Anchor calls this “The Happiness Advantage.”
“The brain at positive performs better than at negative, neutral, or stressed,” he explained in his TED Talk. “Your brain at positive is 31 percent more productive, 37 percent better at sales, and doctors are 19 percent faster and more accurate at coming up with the correct diagnosis.”

Helpful step 1: Take it seriously.

My “Suck it up, buttercup” upbringing has made it difficult for me to open up about any mental health issues. A part of me still wonders, “Why sit around and talk about it? It’s not going to change anything, so why waste my time, money or energy?”
It’s taken me years to confess I’m not 100 percent certain I would still be on this planet if not for my children. The thought of their growing up without me -- and hating me the rest of their lives -- kept me from fully entertaining the idea of suicide. Yet even as I experienced those horrendous thoughts, I believed I wasn’t that bad off. Surely, time would heal everything.
I know now it’s a serious mistake to treat mental health lightly. It doesn’t matter if you believe you should feel happy, you don’t deserve to be depressed, or you ought to be able to walk it off. If you’re experiencing any symptom of depression or isolation, find help. Don’t try to handle it yourself.

Helpful step 2: Rewire your brain.

Professional help is a must. Once you’ve made contact and found someone you trust, you can practice positive habits outside of those scheduled visits. Anchor, the former Harvard psychologist, believes great rewards can come from small steps.
“In just a two-minute span of time done for 21 days in a row, we can actually rewire your brain, allowing your brain to actually work more optimistically and more successfully,” he says. Here are a few ways to get started:
  • Document happiness. Every day, write down three new things for which you’re grateful. Or, write a longer journal entry about one positive experience. This trains your brain to shift away from the negative and allows you to relieve happy moments.
  • Exercise. It teaches your brain that behavior matters.
  • Meditate. This type of deep reflection helps focus your attention and creates mindfulness, releasing you from the scattered brain pattern created by continual multitasking.
  • Express gratitude. Write one email each day thanking or praising a person in your social support network.

Moving forward.

You are not alone. That realization is the single most important thing to remember as you cope with the stress of balancing entrepreneurship and other aspects of life.
When Kander dropped out of the Kansas City mayor’s race, he uplifted military personnel for their bravery. As a person who’s suffered silently from depression, I admire the courage it took for him to share his struggles and admit he can’t do it on his own.
As more leaders tell their stories via public platforms, entrepreneurs will better understand others are feeling many of the same emotions and doubts. Ultimately, this broader awareness will encourage more business founders and partners to seek help on their paths to success.

20 SALARY NEGOTIATION TECHNIQUES FOR A COUNTER PROPOSAL OFFER

Published by  



If you’re one of those extremely talented individuals who constantly have companies fighting over you, you should know how to negotiate the best terms of employment for yourself. Whether that means a big signing bonus, a higher base salary, more vacation time, your own secretary, etc. it all comes down to the counter proposal. Here are 20 great tips to help you negotiate like the pros.

20 Salary Counter Proposal Techniques

1. Don’t begin negotiating until the process is almost complete. Wait for the employer to fully commit to you, giving you more leverage to offer a counter proposal.
2. Don’t sign the original acceptance offer. Once you do sign it, you’re pretty much committed. The best time to start negotiating is once you’ve been presented the offer letter.
3. Upon receiving the initial offer letter, thank the employer and ask for time to consider the package. Being put on the spot will decrease your ability to negotiate (just think about being stuck on a car lot with them beating you down to sign).
4. Do your research. Know how much this job pays, based on your skill set, geographic region, economy (now may be a bad time to ask for that private jet), and other various factors that may affect your ability to get the compensation you deserve.
5. Just do it. While you should be prepared for the employer to potentially walk away from the offer, as long as you are fair in your proposal and justify it with research, you will most likely receive a positive response. One study conducted by the Society for Human Resource Management) are willing to negotiate compensation, only a small percentage of job-seekers actually do so.
6. Negotiate to your strengths. If you’re better on the phone, call the employer on the phone. Better in person, schedule a face to face, and don’t be afraid to write your proposal in an email, this way you can outline all of your thoughts much better.
7. Always ask for a higher salary within reason, than you are willing to accept so when you get your counter proposal, your goal salary will be the ‘compromise’. And when possible, try and demonstrate how your increased salary will recoup itself through additional sales, cost savings, etc. for the company.
8. If the salary offered to you is on the low end — and the employer said there’s no negotiation in the salary (perhaps due to corporate policy), consider negotiating expediting your review period for a raise, a signing bonus. Always negotiate your salary first, if you can, and then move on to other items of compensation.
9. When preparing your counter offer, include the benefits you don’t really want. Use these extra benefits as concessions so you can get the higher salary but don’t need the extra 5 sick days, etc.
10. Even if the salary is non-negotiable, you can still negotiate other items. You can ask for moving expenses, additional paid or personal days, professional training, MBA paid assistance, and more.
11. Never stop selling yourself. You need to make your employer believe that they are hiring the right person, and that this negotiation is only going t increase your level of commitment and value to the company.
12. If you don’t plan to work for the company, don’t negotiate. Don’t waste your time and the company’s time negotiating for a position you don’t plan to take. You’ll soon realize what a small world it is if you start burning bridges with people in your industry.
13. If you have multiple offers, don’t start a bidding war. Putting companies against one another and asking for increasingly higher amounts from both sides rarely works out. What is does is frustrate the companies with you and makes you less desirable to a company. You should have backup plans when negotiating so if one proposal doesn’t go through, you have other desirable options available.
14. Don’t enter negotiations with the wrong attitude. Always have in the back of your mind your goal you want to accomplish with your negotiations. This should be a win-win scenario. You want to get a better deal which will in turn help the company in the long run based on your happiness with the position.
15. Some employers will just not negotiate. Based on economic factors, corporate policy, job supply, etc. will give the employers a considerable amount of leverage and will simply not negotiate and may deny your original job offer. Unless your skill set is highly valuable and you present a unique opportunity to the employer, be sure not to lose a job over it.
16. Never make demands. You may be working for the person you’re negotiating with directly, and you don’t want to start the relationship off on this note. Instead, raise questions and make requests. How much does a typical person with my qualifications earn in this position? Do you ever award signing bonuses? Moving expenses? Additional time off?
17. Be prepared for any possible reactions to your counter proposal. They could completely deny you the job or could offer you everything you’ve asked for in the position.
18. You have to be wiling to walk away. Just like at the car lot, when you decide to leave, they start beginning to walk to finally deal. You don’t want to show that you really want the job to the point it compromises your ability to negotiate effectively.
19. Once the employer agrees to your requests, stop negotiation. Once you get what you requested, you can’t start asking for more and more and more.
20. Always be sure to get your final offer in writing. Verbal agreements aren’t worth much these days, so after the negotiating is complete, be sure to have your final offer delivered to you in writing, and make sure to review everything before finally signing it.
