There are things you can control and things you cannot control.
If you focus too heavily on those things you cannot control, it can lead to an overwhelming amount of frustration and anxiety.
Choose instead to focus your thoughts and efforts on those things upon which you can have a positive influence.
There are plenty of those things, and by giving your energy to them you can quickly and significantly improve the quality of your life.
Stop worrying so much about what others are doing wrong. Instead, put your time and effort into discovering what you can do right, what you can do well, and in using your unique abilities to create excellence.
Whenever you feel yourself getting anxious or frustrated by something that’s beyond your control, stop and take a fresh look around. There’s something you can do, right then and there, that will make a positive difference in the world.
The more you make use of the positive power that you have, the stronger that power will grow. There is always something you can do, and it always beats complaining or worrying about those things you cannot do.
Do what you can, when you can, where you are, with what you have. You’ll find that it can make an enormous difference.
