Know You have Total Control how you react to anything, what your perspective is, how much something is going to affect you... if you realize you have that control and USE IT!
This is TRUE for everyone. It isn't a theory or a supposition, it is a scientifically proven fact. You are in Control of what you think and how much something affects you. You control how you look at things, your perspective, and how you react to everything in life. When someone "angers" you, you are really just allowing that to happen.
