I teach because I cant' keep quiet because I feel that I have something terribly important to communicate, because I believe in what I'm doing, because I am still scared to death every time I walk into a classroom, because I think I can make a difference in people's lives, and because I still think it is the greatest life in the world. The older I get the more I love it.
