Serenity Prayer
God grant me the serenity to accept
The things I cannot change,
The courage to change the things I can,
And the wisdom to hide the bodies
Of the people I had to kill because
They pissed me off.

And on the subject of assuming responsibility...
The actions of those in your circle are generally influenced by your own behavior and a certain measure of responsibility must be assumed.
For instance, at work they may circulate rumors that you are lazy and get nothing done. This may be largely untrue, but if there were a couple of instances in which you missed a deadline of failed to respond to someone...there is at least >some< basis for that attack that you are, indeed, responsible for. Own up to these things instead of being dismissive. And DO NOT blame them on whatever the condition du jour is. Accept them as part of you and your realm of control and deal with them.
