"The longer I live, the more I realize the impact of attitude on life. Attitude to me is more important than facts.... We cannot change our past...we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is play on the string we have, and that is our attitude. I am convinced that life is 10 percent what happens to me and 90 percent how I react to it. And so it is with you... we are in charge of our attitudes."
