This reminds me of the time in my doctoral program when I turned in a draft journal article to my advisor. He returned it a week later with no marks or written commentary whatsoever, other than telling me "do it again." I asked what was wrong with it and what I needed to do differently on the next draft. He replied "this isn't excellent. Don't give it back to me until it's excellent." I asked what excellence entailed and he said "you just know."
People ask me if I learned anything in grad school.
