I do appreciate that this advice is usually given in good faith, but I have honestly found it to be the absolute least helpful social advice for me. It's usually in conjunction with some variation "just do what feels natural". However, I've lately realized just how much processing of information I have to do for everyday social situations just to figure out what is "natural". I've only realized it this recently (even my AS diagnosis didn't spawn this realization) because it's never been an issue. I can process things like patterns in behavior and the context of the interactions fast enough to where it appears intuitive, and I can recall all this information later so I don't have to process all that again when I encounter a similar situation.
Usually, "overanalyzing" leads to anxiety and indecision, which is why this advice is given to me so often. But for me, the opposite is true: the more data I have to process and to notice patterns in (this processing is why I've never had trouble with accidentally breaking unwritten social rules, although I still do if I think they're sufficiently stupid/trivial), the more comfortable and at ease I am with making a social decision.
A good example is a phone call. If I'm not expecting it and it's from an unknown number, I can't make myself answer it. I don't have any idea of what to expect, so I freeze. But if I've had some advance warning, I can go over everything in my head and feel comfortable answering.
