When I was a child, I thought of my Delta town as the center of the universe, but now I realize how little I know about the universe. As a child, I thought I was immortal, but now I recognize how limited a time we all have. As a child, success meant scoring A on every exam, but now I take it to mean good health, close family and friends, achieve- ments in my work, and helping others.
