I like the parallel of Michael Phelps. It is relatively well known that Phelp’s unique physical proportions makes him physiologically advantaged in competitive swimming and yet to be an elite swimmer at the highest level he had coaches pointing out any minor inefficiency in his stroke mechanics. There is no doubt that many individuals can learn most everything they need on the internet or with a library card, however there is a real advantage to receiving feedback and having an expert to help guide your education. When I was in graduate school I was exposed to areas of study I would have ignored or glossed over. Areas that I thought I knew enough about and understood, but was actually woefully ignorant of.
