Philosophy - Regrets

I know a lot of people that use the word regret and live with regrets. And I just disagree with that 100% because I feel like whatever choice you made in the past, you made the best choice that you could, giving the circumstances in any possible moment that you could make. And if you just shift the word regret into “I made the best possible choice I could at the time” you don’t have to live with any regrets and it also helps me understand other people and why they do the things that they do. They’re just making the best possible choice for them. I don’t have to think about “why?” or “what they’re doing”, I just don’t have to think about it. It’s so incredibly liberating to not have any regrets and also sometimes just not be mad at people because they’re just doing the best that they can, just like you.
