I guess that's what's called learning curve.
I think it's called life but let's be honest, there's many who never learn and mainly stay stuck. Say they can't change and so on...
Coming to think of it. There are million of things that I would have done differently now. But back then I think I did the best. 🤣🤣🤣
Not sure if that make any kind of sense
Very normal, although I tend to think that everything happens for a reason. We can't change the past but we can control the now ;<)
