I have had lessons which cost $500 an hour.
Good grief! Who in the name of all that's unholy was that with? And can you honestly say that you got anything out of it that you couldn't have worked out by yourself?
the connections you can make with a famous teacher is invaluable.
Oh, you mean $500 an hour breaks down as $100 for a lesson and $400 bribe for the teacher to schmooze for you. Fair enough.
