" Often the reason we won’t say no is that we are afraid. We fear disappointing people. We fear being passed by. We fear missing out on a good opportunity. But at some point every leader must come to grips with the fact that there will always be more opportunities than there is time to pursue them. If we don’t choose our opportunities carefully, we will dilute our efforts in every endeavor. Refusing to say no eventually robs a leader of his ultimate opportunity—the opportunity to play to his strengths. Choose your opportunities carefully. Many opportunities are worth missing. Just say no. "
