I want to set an example. It's the macho in me - the ego. To get up every morning and leave a warm bed, a hot woman, and go into a cold gym - that's dedication. Nobody else is going to do it for me. There are people who go to church and they pray for good health, all the time they're breaking nature's laws.
Sleep is irrelevant.
When I have something to do, I can get by on a few hours sleep. I don't worry about it. I think about doing what I have to do and that keeps me going. The reason people sleep so much is because they're bored. They have nothing to get excited about.
