What I learned from my work as a physician is that even with the most complicated patients, the most complicated problems, you've got to look hard to find every piece of data and evidence that you can to improve your decision-making. Medicine has taught me to be very much evidence-based and data-driven in making decisions.

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?

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.
