One thing you gotta take into consideration is that it's professional wrestling, and you know it going in. There's dangers to every profession, and our particular profession, concussions is one thing.

When I was with WWE before, I was a big guy throwing people around - power moves. Then after that, when I left WWE, I was like, 'I still enjoy professional wrestling,' but some of the smaller guys look up at me and say, 'I don't wanna wrestle him. I don't wanna get thrown around by that guy.'

My philosophy is, if you work as hard as you can, you give yourself as many opportunities as you can to be successful and lucky.

One of my first overseas trips with WWE was to France. I walked out of our hotel, and I see a little kid walking toward me with his mom. He gets a couple of steps past me and he stops in his tracks. I see his mom do a little bit of a double-take, then he runs over and just grabs on and starts hugging my leg as hard as he can, then he starts crying.

Not to be narcissistic, but I truly believe in order to make yourself better, you should see what you did before and what was good about that and what wasn't - same way a football team plays a game and then they go back and watch film.

When launching a product called an Energy Drink and named Red Bull, a product that stimulates body and mind, it is a short step to the roots where Red Bull came from. We have been doing this for 20 years - now it's called adventure sports, extreme sports, and outdoor sports.

When you think about little league football, high school, and even on to college even more so, you're dealing with a lot of guys that are prideful, that think they're the best - a lot of alpha males. So, typically, you've got to have a guy that can control those guys, and, when he talks, they know he means business. He's a serious guy.

Ever since I was a little boy, I had my eyes set on being able to say I was a professional athlete. I worked hard every day to make sure that it became a possibility and sacrificed a lot for the game of football.
