A great conductor once said to me, "I really like your new voice teacher, he really knows what he's doing. Not like your last voice teacher, he didn't know anything. Your first teacher was on the right path, too bad you didn't understand the message yet."

I heartily agreed the whole way through, until he revealed he had no idea who any of my teachers were. It's just that everyone feels that way.

The lesson is: blindly following a series of teachers like oracles is the way of the beginner. The path of the master is accepting that YOU are your own teacher, and everyone else is just providing tools.
