From one of my all time favorite books:
"As A Man Thinketh"

This quote is included in a larger excerpt towrads the end of Chapter 23 in my book. My book actually teaches you how to do what Allen and others merely tell you is a necessity - be in control of how you think. 

Take responsibility for everything that happens in your life - that gives YOU control to change it! And the easiest way to do that is to change your language. ❤
