Regret is useful for about a week. After that it’s just rent. Take the lesson and stop paying.

Regret has one job and it does it quickly. Within about a week it has handed over the lesson: what you would do differently, what you missed, what you will watch for next time. After that it keeps collecting from you every month and delivers nothing new, which is a strange arrangement to stay in.

If something is still circling, write the lesson in one sentence and put it somewhere you will see it. Then, when the replay starts, read the sentence instead of running the film. You already have what it came to give you.
