But through grit, determination, and a ceaseless will to evolve, David rebuilt his firm, one client at a time. By transitioning from investment management to holistic financial planning, David grew his firm's assets to $500M in the following decade.

David's intelligence, wit, and resilience are just a few of the qualities I love about him. I'm so glad to have captured his story in the most recent episode of "To Grit, with Grace: The Entrepreneur Sessions."

René Syler co-anchored the CBS Morning Show from 2002-2006. Having started out as a local news anchor in Reno, NV, her ascent to the network level was meteoric. So, when she lost the job amid a network shakeup, it was that much harder to take.

René's story is one of high highs, low lows, setbacks, and transformations. A Black woman, René long faced pressure to conform to conventional beauty standards, which lifted when she transitioned out of network life. Now a one-woman, full-service production company, René's broadcast life continues — only now, it's in a way that lets her be her natural self.

Erin came to New York City at 18 years old with only grit and determination to fall back on. Needing to pay for food, housing, school — and fast — Erin learned how to hustle. That hustle would pay off in 2014 when, after a year of traveling the world, Erin started down the entrepreneurial road, one beset by challenges internal and external.

Erin's company, Dynama Insurance, is more successful today than ever. Her story is a must-listen for young entrepreneurs — especially women — hoping to make their mark on the world.

Michael's radical injury prompted a radical shift in perspective. It took numerous surgeries to get his body bike-ready; it took deep emotional labor, including a redefinition of his values, to resume life with peace of mind. And when those values didn't fit with his corporate job (Michael was a VP at a global pharmaceutical company), it meant striking out on his own.

Now a successful entrepreneur twice over, Michael's story illuminates the full spectrum of the entrepreneurial mindset: from chaos and self-doubt to self-belief and growth.

Aged out of her career and reeling from her husband's financial infidelities, Lisa Weldon found herself 58 years old and in need of a new start. While all of us take recovery one step at a time, Lisa took it one step further, walking every neighborhood in New York City, and building an online following around her blogs and photographs.

Julie Davitz literally grew up in a barn, believing that the best thing in life would be to marry — and marry rich. In spite of her spunk, her tenacity, her independence, Julie took the safe road.

But looks, as we know, are often deceiving. The safe road can often be anything but.

You'll hear how Julie went from a Cinderella life, to an absolute wreckage, to what sounds to me like sheer hell. But it was hitting that bottom of desolation that brought her where she is today, running global impact investing company Plus Media Solutions.

There's no guidebook for grief. People on the outside can give support, but the real work happens inside. It's hard enough when a relative dies at a ripe old age. But when someone we love is taken from us unexpectedly, and prematurely, the difficulty multiplies.

That's exactly what happened to my guest this week, Lynn Thomas. Just as she was starting her business and a new romantic relationship, homicide took away someone she loved. It pushed Lynn out to the edge of mental stability. But while she was out there, she developed depths of compassion she says she might never have otherwise known.

In 2008, the financial crisis brought Rachelle Fender's career to a halt. But she'd seen devastation before, and she realized that this time, the worst news could actually be the best news — with the right mindset, and with courage. Rachelle found her life's purpose working with the humanitarian organization appropriately named Unstoppable.
