I am a perpetual "YES" man. No I don't mean I never disagree with you, but rather any time you ask me if I want to do something like lecture, write an article, join a committee...I tend to say yes.
Then comes the "hit your forehead with the palm of our hand moment" when you realize that you couldn't possibly do one more thing with your current commitments!
This article will help me say "no" more often..........maybe. DM
