Too often we get distracted by what is outside of our control. You can't do anything about yesterday. The door to the past has been shut and the key thrown away. You can do nothing about tomorrow. It is yet to come. However, tomorrow is in large part determined by what you do today. So make today a masterpiece. You have control over that.
