Learn to say no. Say what you mean and mean what you say.
Often we say yes because of the fear of authority, the fear of
hurting someone’s feelings, or worries that we will let someone down. But every
time you say a yes that you don’t mean, you’ll end up doing a half-hearted job.
And then you are unhappy that you said what you didn’t want to say, and you are
unhappy that you did such a lousy job of what you said you would do.
