If analogize this to chess, here is what I would say: 1. beginners are learning the rules 2. intermediates are learning the principles 3. experts know the principles 4. masters know when the principles are wrong Doesn't sound as nice as they way you wrote it.
I got in a lot of trouble reading master books in chess when I needed to be reading expert books. Similarly in business I read a lot of master and expert books when I should've been reading intermediate or beginner books. Experience and hard lessons did the trick though.
