When you stop being nervous is when you should retire. I'm always a little nervous for anything I do because when complacency sets in, that's when I feel it's time to move on to something else.
In WWE there's a huge degree of acting you need to have to become legendary, to become popular. You have to become a great actor in WWE and that's something I've honed from a young age. I could never be the biggest guy on the show when I first started wrestling; it was all about the giants. But I could have the biggest personality, the biggest character.
