Instructors have a unique situation where they have worked with many students of the game and have come across many different problems and issues. People who offer advice but don't teach certainly have something to offer but they are missing that element of experience with many different types of players.

Not having a go at you personally (as I haven't read many of your posts) but from what I've seen I'll take Pidge's advice ahead of a lot of the instructors on here.
To the OP, I'd say just read Pidge's first post. It answers the whole question well, IMO.
