Whenever something bad happens to us, it’s natural to examine it. To pick the event apart, dissect the circumstances, dwell on the implications. But there are two ways to do this, and only one is healthy.
People who examine their failures fall into one of two camps: people who are looking to change the past, and people who are looking to change the future.
Some people examine their failures down to the molecule, but they’re not looking for wisdom. They’re looking for some way to make the failure not a failure. They want to find some piece of evidence, some context, or some hidden agenda that changes the nature of the disaster from one where they fell short to one where it wasn’t their fault. They’re trying to change the past.
The other camp is full of people who examine their failures trying to change their future. They’re not looking to alter what happened in the past, they’re trying to make sure it never happens again. They accept what happened as the first step to understanding why it happened, and understanding why can lead them to doing better in the future.
Everything you’ve ever done happened in the past, and it’s natural to draw on experiences. So you’ll “think about the past” with some frequency. Are you doing it to learn from it, to try to change your future? Or are you trying, against all hope and reason, to hew a new shape from stone already cast?
You can’t edit the history books. But you can read them, and write the ones yet to come.
