There is nothing we can do about yesterday. We can’t go back and participate first-hand in its joys, or go back and change things to ease our sorrows. The old days are dead. There is nothing left but the new days. Tomorrow is there for our taking. It is ours to take advantage of, or to let it slip by and waste it as many of us do. If you want next week to be better, it is important to make tomorrow and the next day after and the next day after that better. Living in the past keeps you from living in the present and making a better future.
