I knew right then that I wanted to be a part of something that meaningful. I wanted to have something I was so passionate about that I'd be willing to risk everything for it. I wanted to know that if I ever got killed, I got killed doing something worthwhile. The kid who looked up at the moon and wasn't afraid to dream - I decided that part of me deserved a chance. I sat there in that reception area, watching the crash footage play over and over again on the television, and that was when it hit home for me: you only have one life. You have to spend it doing something that matters.
