One the best quotes I've ever heard and always remember comes from one of my favorite Disney television shows, The Suite Life of Zack and Cody. Although that that episode a while ago and when I was pretty young, for some reason it stuck with me after all these years. "If you can conceive, you can achieve and then you'll be the pilot of your own life!"
It comes from the first season when one of the main characters, Cody Martin goes to a seminar and decides to become a motivational speaker, by repeating what he's learned to the various characters in the episode. When I was younger, I used to repeat the line as a joke and laugh at all the trouble Cody had caused everyone.
