What's important is that people realize that I can't be put into a box musically. I've studied all forms of music; I know probably more Jay-Z songs than the biggest Jay-Z fan. I've studied R. Kelly to the Isley Brothers to Stevie Wonder to Sting and Sade. You don't have one personality every day. You don't have one mood.

Barriers have been broken: rappers are singing, and singers are rapping. You might catch a rapper on a rock song, a pop artist on a hip-hop song - there are so many different things that are going on today. That is the same way in which we live our lives; we're all over the place. I like to try different things.

Singing is all about certain inflection on certain lines. I used to listen to tapes of everybody from Michael Jackson and Prince to Earth, Wind and Fire. They would have different vocal inflections. If the line insinuated pain, they would cringe on some lines.

The thing that is cool about my come up is that I dealt with fame and having money gradually. It didn't happen overnight. It was something that took a while to happen. It was something that humbled me and made me very appreciative of my blessings more than I would have been if it had happened faster and easier.

I'm heavily influenced by European and American cinema, but the further I get in my career, the more I find myself looking back East for inspiration.

If you're an actor, and you're selfish and not strong, it's difficult to maintain a good personal life or a solid career, and I was selfish and had a lot of anger that went way back.

So when my film career took off, I always felt like I was trying to play catch-up because I hadn't studied acting before. I didn't know how to manage money or my career. When I look back, I think I was a little bit shell-shocked.

I have an expression I use as I've gone around the world through my career: 'You never tell another man or woman what's in their interest. They know their interest better than you know their interest.'
