When I was a kid in school, I found myself constantly thinking about tomorrow--what I intended to do as soon as I could get out of the classroom and get moving.  The young often dream of tomorrow, thinking of what they are going to do, and the old often focus on yesterday--what they have done.  You know the attitude, "The older I am, the better I was!"  With each telling of the story, the fish gets bigger or the hero gets braver.
