>I overthink everything all the time and there are still many things I miss and do wrong

Maybe you are just thinking? It only becomes overthinking when you have been at it for "too long". As in, it is not reasonable to guess that thinking more about it will be of value.

Of course, knowing when that is the case is hard. IMO we should spend more time figuring out when it is overthinking than warning people about overthinking.

I mean I have a clinical problem with overthinking (I am diagnosed with OCD) and I'm not disputing at all there are cases where overthinking is irrational and unproductive. I'm just pointing out that just like there are risks of overthinking, there are also risks of underthinking. And I usually see advises about how to prevent overthinking, and not underthinking. If I were to make a perfectly rational choice, I'd risk overthinking more than the opposite. So, although balance is ideal, if a balance is not possible (you don't have enough data to make a perfect decision) then I think, rationally speaking, you want to err slightly on the side of overthinking.
