Seems somewhat related to the sunk cost fallacy, although not exactly the same. But like the author says, it's irrelevant what you did or didn't do in the past

Seems somewhat related to the sunk cost fallacy, although not exactly the same. But like the author says, it's irrelevant what you did or didn't do in the past, or where you could have been now if you'd acted differently. Except in as much as you can learn from your past behaviours and try to encourage the ones you find increase your satisfaction and control the ones that do the opposite. But there's no point at all in worrying about what you did or didn't do in the past, since all you can control is the future!
