My dream job was to work in an ice cream shop. Two weeks and five pounds later, I realized it wasn't for me. For many years, I had planned to be a corporate lawyer. As luck would have it, other than a summer internship, I didn't end up doing that either.

My greatest inspiration is my mother, the bravest person I ever knew. She overcame incredible odds, worked while raising two kids, and made it all look incredibly simple. Even in her final days succumbing to cancer, she fought like a champion.
