My experience of this short life (I'm only 51) is that the fault lies in the adjudication process of our actions. If you look back and judge everything as Good or Bad to try to inform your future, you're setting yourself up for disappointment. You can't replicate the Good and avoid the Bad because you have no idea what the NEW outcome may be.

It's like the Trolley Problem: impossible. Steer to the right and kill five to save one? Sure, the one might have saved humanity, but one of those five might have, too, or no one, or everyone. So you choose and you regret, or you choose and accept? (It's not like you tore out the brakes) (and what does it even mean to "save" anything anyway?).

My reading on Kundera's quote: Don't Judge. Absorb, but without the assignment of Mistake or Success.

Here's another quote: "There are no bad things, just misguided perceptions." I bring it up and people argue it: The Holocaust, Slavery, Ukraine, that woman who drowned her four kids, etc.

Of course, I wholeheartedly agree that we all share the perception that these are absolute atrocities. But the exercise is to contend with the idea that we don't know how the future will be shaped because of them. Israel. Equal rights for all. Unequivocal freedom from a nasty super-power. Even the four dead kids may lead to more money and awareness being funneled into mental health issues and the plight of the overstressed parent.

We Don't Know.

Instead of being afraid of your choices and seeing how they propelled you into doing things that you regret, honor it. You are not a collection of wrong and right turns. They were ALL RIGHT, at the time, based on the information you had and the level of your intelligence, spiritual awareness, influences, and being.

Don't regret. Learn, and go forward with clarity and confidence.
