I did a business in a box called College Pro Painters. They taught you how to paint houses, how to hire and fire, how to sell, how to deal with customers. You got a one-year franchise. It was the hardest year of my life in terms of hard work. I won manager of the year. It was very successful.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.

As a kid, I always idolized entrepreneurs. I thought they were cool people in the way that I thought basketball players were cool people. It's cool that some people get paid to dunk basketballs, but I'm not one of those people.
