When I was 7, I was taken into this ice cream shop. There was a 10-year-old in line in front of me, and my father says to this little boy, "What do you want to be when you grow up?"
And the little boy says, "I don't know". My father turned to me and said, "I don't care what you want to be in life, but I never want to hear that answer from you. I always want you to have a goal".
So I decided in that ice cream shop that I wanted to be a doctor. Later, in high school, I decided I wanted to play pro football. Go figure.
