If you are good at something and can't articulate why your consistency is going to be pretty poor. Speaking from experience, I took a bowling class in college and got good enough that I could have "good days" but I couldn't tell you what I was doing differently on those days versus my "bad days". The lesson I took from that was that I was still a pretty terrible bowler and needed a coach to explain to me what I was doing wrong.
