Here’s something obvious: regret is irrational.
The past can’t change; suffering over the past is imaginary.
I don’t regret anymore.
Here’s the thought experiment:
“If that event (of the past) changed, my life would be completely different now.”
The other event will lead to other events, which lead to other events. My life would be shaped by completely different coincidences.
The butterfly effect is powerful; I have no idea how the other scenario would’ve played out.
To change that event, I have to give up all the positive events, too.
I can’t just change that one event and keep all the good events + the present.
I like where I am today. So I’d rather not change the past.
In the same way, I can’t complain about anything before I was born. I wouldn’t exist!
So, I get to regret until 2 days1this is completely arbitraryafter the event. Then no more.
