Well put. I wonder if a lot of this comes from classical piano players (which there seem to be a lot of, proportionally?) assuming that everyone who learns piano is necessarily aspiring to play those super difficult classical pieces one day. I've started picking up the piano with jazz in mind and it's hard to tell if a lot of the advice out there is spot on and I'm worse off for ignoring it, or if it's really just not relevant to me because I don't intend to play Bach or Mozart. A lot of it _feels_ irrelevant, but I hesitate to dismiss it when it's coming from people who are clearly a lot more experienced than I am.
