You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?

I write for kids because I think the most interesting (and most humorous) stories come from people's childhoods. When I was writing 'Diary of a Wimpy Kid,' I had a blast talking on the phone to my younger brother, Patrick, remembering all of the things that happened to our family when we were growing up.

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.
