Last week I shared my friend Margaret Maggard's bright and happy bungalow filled with family history and vintage treasures. This week, I'm diving deep into Margaret's experience as an entrepreneur. It's been a few years since Margaret retired from her jewelry design business, but her transition from a stressed-out mom stringing beads for relaxation to a successful entrepreneur with a long list of customers including First Lady Michelle Obama is fascinating. Those of us who love watching "Shark Tank" or listening to "How I Built This" will find Margaret's story compelling and full of lessons.
