To disappoint in the eyes of another is pain, to disappoint in the eyes of one's self is to suffer.
Going into anything I do, especially competitive activities, I always give myself goals. I set my goals reasonably, never so far out of reach that they are preposterous, but not so shallow that they don't make me strive for a little more. Normally I am good about meeting them, at least a majority of them, at least the major ones; this weekend I met none.
