Discipline is doing what you really don't want to do so you can do what you really want to do.
I actually ran in junior high school a little bit, you know, like most kids do in track and things. Then I got out of it and just trained for football and played ball for so many years - high school, college and the NFL.
I've always liked to run. I did it from a conditioning standpoint, you know. I really enjoyed running, and I do it to stay in shape.
My kids are athletic, but they don't run.
