Hindsight is a bit of a folly in the sense that, for me anyway, it just makes the guilt of past mistakes sharper. For example, hypothetically, I shouldn’t have/said/done/written this. Or that. But I did.
Most of us know the experiences that hindsight gives us – regret, new wisdom and, sometimes, a determination to do better in the future. Why else would so many of us say, or at least think, ‘In retrospect, I would/should have done this differently.”
None of us can predict the future any more than we can change the past.
In hindsight, I would have given Anthony that ultimatum years before I did and, by now, we would have several children. But we wouldn’t have Ming.
In hindsight, I would have noticed how ill Anthony was becoming instead of putting it down to ageing.
In hindsight, I would have loved him more than I already did.

I think we all live with these things, but can’t do anything to change them. we didn’t have the life experience and information we have now, in order to have done things differently. things happened as they were meant to, and we did the best with what we had as our reference points at the time and have to try to let that go and move ahead – not always easy, but we keep trying
I find myself looking back too many times and wishing this or that but we can’t change a thing and i really wish I would just look at today because we really can’t predict our future either
You are very philosophical about it all, bravo!
We are our decisions good, bad or otherwise………….
Except that and be happy , as you have done
Hindsight is almost worse than making the original mistakes in my experience.
