> I have noticed a certain phenomenon where people who are bad at something read books about it to compensate, and then having read books on the subjects start considering themselves experts on it and preach to others, closing the loop from descriptive to prescriptive.

I had a bad case of this, I did it a lot. Fortunately, some people made me aware of this tendency. Now a lot of those things I've learned are natural as if they've always been part of me. To be fair, there's 10 years in between both points.
