Slow down.

Before you speak, listen to what is being said.  Before you react something, think it through first.

Then think it through again.

If you still feel you need to react, okay, go to it.

 If you’re going to criticize, wait it out, hold your tongue and see the above to steps.

Pick your battles carefully. Sure, you can win certain struggles but as a natural born fighter I can tell you this; sometimes having peace in your life is a lot better, a lot better, than being right.
