Defining Oneself

I sometimes wonder why I continue to train. Often its not because I enjoy it, as a matter of fact more often than not I would prefer not to put myself through the effort. I think what drives me, or what motivates me, is the fact that in a way my sport defines who I am. I like to consider myself as a triathlete, regardless of what standard I compete at, or how slow I am, I am a triathlete. Without my training, my sport, my level of self esteem would drop and I would cease to picture myself as the person i want to be.

This is all probably ego but thats the way I am.
