stop worrying about things I can't control

People I work with are critical, cynical and sometimes downright mean. I have to remember that it is not my problem, but theirs.

Done this sufficiently to consider it as complete. I am aware that some things in life I can’t control. Instead of agonizing over what I can’t do about something I try and plan my reaction to what may or may not happen so I am prepared either way. The other thing that has helped is confronting the problem head on and talking with the people involved instead of worrying about the situation and ruining my evening or weekend pondering on the what-if’s. This has helped me a great deal in my career and my personal life.
