What lessons did you take from your regrets?
The biggest lesson is that life is too short to have regrets. I have to remind myself of this all the time. So I did some regrettable things. Can I change that? No. Time to move on then.
Another is that the past is in the past for a reason. Shit happened. A lot of it. Has it ruined me? A bit perhaps, but not beyond recovery.
So now, I try to do things purposefully and mindfully. I am not reckless like I was in my youth. This leaves less room for regrets.
As the Fates Would Have It 
I think it’s true what you said about getting older. We learn (well, some of us) to not be so reactive, to stop and consider before we act.
We all do things we later regret. But if we learn from oer mistakes then it was not a wasted experience.
