We should try our best not to dwell on past mistakes or past events. What’s done is done and we cannot change it. Whether it was in our control, or out of our control, it’s in the past for a reason. Don’t look back, you’re not going that way.
Of course there are special circumstances in which we cannot simply “let things go,” but I’m speaking in the context of day to day exemplars. Whether it’s being frustrated with a friend, not getting a promotion at work, saying something you should’t have, etc. We should not carry around guilt, anger, or stress with us, it’s not healthy. Especially small, minuscule incidents that don’t change the course of our lives.
The point I’m trying to make is it’s important to forgive others for their wrong doings, but it’s just as, if not more important, to forgive ourselves when we’ve slipped up, and made mistakes. We shouldn’t pour energy into the past, it’s done with, rather focus on the future to better ourselves and those who matter in our lives. We all have our struggles and make mistakes, and we’re expected to, we’re human after all.
