It's really cool to see how many people try to imitate me or wear my stuff. I get a lot of Instagram videos of people doing my entrance. I think that's so cool. To see the variety of people, little girls, guys, doing it. I never really thought that would happen. It's amazing.

By the time I was 10, I was doing plays for Phoenix theater. My first lead role was as the Stinky Cheese Man. I got a taste of the limelight, and I just couldn't stop. It was a way for me to be the artistic, geeky kid that I was, and not get beat up.

Kids will come into my boxing gym with no discipline, and then you teach them how to focus and love what they're doing, which then travels outside into their home and work life.

Some years ago, I fired my agent, Andrew Wylie, alias The Jackal. I want to stress this wasn't an amicable parting of the ways or a hankering on my part for fresh representation. I fired him because his agency wasn't doing enough for me.

If you didn't have patents, no one would bother to spend money on research and development. But with patents, if someone has a good idea and a competitor can't copy it, then that competitor will have to think of their own way of doing it. So then, instead of just one innovator, you have two or three people trying to do something in a new way.
