For the past 33 years, I have looked in the mirror every morning and asked myself: 'If today were the last day of my life, would I want to do what I am about to do today?' And whenever the answer has been 'No' for too many days in a row, I know I need to change something.
So, I went through life constantly practicing this model of disciplinary approach. Well, I can’t tell you what that’s done for me. It’s made life more fun. It’s made me more constructive. It’s made me more helpful to others. It’s made me enormously rich.
