Memory can be used for good or for evil. If you use your past as a source of learning, it’s worth remembering. If, however, all you do is mull over your mistakes and punish yourself for your failures, it’s a waste of time. Rehashing failure can paralyze you in mortal fear of making another mistake, which, of course, just makes the feeling worse and practically guarantees future letdowns. The key to making meaningful changes is to pay more attention to the future than to the past. Have you ever noticed that the best athletes also have the shortest and most selective memories? Instead of dwelling on a missed shot or a flawed dive, they concentrate on making corrections and getting the next one right. It’s as if the failed attempt never happened. It’s forgotten and they don’t fear trying again. If you mess up, even in an epic, life-altering way, work hard to leave it behind and concentrate on the possibilities yet to come. Tomorrow is much brighter when it’s not smeared with a fixation on yesterday.
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 2 Corinthians 5:17
