Since the baseball season is approaching its climax (or its nadir, depending on your point of view), I thought it good to post this quote that comes from baseball, but has a great deal to say in any situation:

All blame is a waste of time. No matter how much fault you find with another, and regardless of how much you blame him, it will not change you. The only thing blame does is to keep the focus off you when you are looking for external reasons to explain your unhappiness or frustration. You may succeed in making another feel guilty about something by blaming him, but you won't succeed in changing whatever it is about you that is making you unhappy.
