William Loopesko had a great-paying job, a house in trendy Denver, and a girlfriend: the perfect Facebook life. But he hated going to work. One day, hiking with his dog, Clovis, he got an idea for a new company. His new purpose changed everything.

We talk about William's transformation from engineer to CEO and entrepreneur, and what it takes to live a good life with meaning and joy.
