Growing up in a group home, and with an undiagnosed learning disability to boot, the odds of success were not on my side. But when I joined the high school football team, I learned the value of discipline, focus, persistence, and teamwork - all skills that have proven vital to my career as a C.E.O. and social entrepreneur.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
