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.
