It was interesting, but other than the part about developing a genuine interest in what other people like to do I found it pretty difficult to implement most of the advice.

I'm autistic though. Knowing what to do is far easier than doing it when you have crippling social anxiety.

I do think that one bit mentioned above was incredibly helpful though. I have quite a few more friends than I used to. I was actually always interested in most conversation topics I just started paying more attention to when its my turn to talk and let other people drive the discussion.
