Self-Mastery 

"Self-Mastery is the art of being totally accountable. It is the inner focus and moment-to-moment disciplining of the only four things that I have any control over; my thoughts, my words, my feelings and my actions. I have no control over anything outside of myself. It is through the constant moment-to-moment practicing of whatever I desire to become mastered in that I actually begin living and radiating the result. Whatever I practice over and over, whether positive or negative, I will truly begin to master. I better be willing to accept every single result that comes from every single choice that I make. I believe that my current reality is the sum results of every single choice I have ever made. Therefore, I am in control of my destiny and my life is exactly as I create it."
