All worries fall into two categories, stuff you can do something about and stuff you can’t. We all spend too much time and waste too much energy attempting to change what we cannot change. It is a major cause of stress and frustration.

If there is somethings you can do, do out a list and get to work. If there is nothing you can do, forget about it and move on, and i good way to doing that is just get busy. Get involving in doing something that take all your attention.
