I've also learned that my memory may be completely different than reality. I've decided that my brain did that for a good reason (perhaps survival of that moment) or maybe it's just being an asshole again. In either case, it's made me more humble and less insistent that I'm correct. I've also put less weight on the past. There's nothing I can do about it, except learn from it. And I feel like I can learn no matter how I might mis-remember my alternate universe self, so I care less about what really happened.
