It's funny you mention taking advice from successful pro athletes. I'm reminded of a great essay, "How Tracy Austin Broke My Heart" by David Foster Wallace. He writes about his admiration for a successful pro tennis athlete, her intensity and dedication to her sport, and her strangely vacuous response to the question "How do you do it Tracy?" - which she answers with some vague platitudes. His point is: very successful people are so busy being successful, they're so deeply immersed in their craft, that they don't seem to even have the conscious introspective wherewithal to articulate what it is they're doing. Everything they know about their craft and their life is just so tacit to them. They've either never taken the time to really introspect, again because they're so caught up in just winning and getting things done, or they're just genuinely incapable of gleaning any wisdom from what it is that they do. So maybe it's not particularly useful to take advice from these people after all. Now, this is probably the case for most such people, but there is a very small minority that do eventually cultivate the ability to articulate their internalized understanding and wisdom of their success to others. Maybe PG is one of them. Maybe not.
