Just Say No!

I know that saying no is the basis of the abstinence campaign for teenagers, but for me, it is a lesson that I must adopt and implement. I am completing the work on a huge obligation, for which I should have "just said no!" And I always feel guilty if I have to turn down a sub request for a class or volunteer gig; I must "just say no" without feeling guilty or needing to give a big reason to justify saying no. I am practicing......no, no, no, thanks for asking.
