I have no way of knowing if this is true, but I just heard a great story about an MIT student who practiced a daily ritual his entire summer.

Every afternoon he would put on a black and white striped shirt and go to the Harvard football field. He would walk up and down the field for ten or fifteen minutes throwing birdseed while blowing a whistle. Fall arrived, and with it, the first Harvard football game. They say after the referee walked onto the field and blew his whistle it took an hour to clear all the birds off the field.

Like I said, I don't know if it's true -- but I hope it is.
