Failure is not the crime. Low aim is.

It matters not the subject taught, nor all the books on all the shelves, What matters most, yes most of all, is what the teachers are themselves.

It's not what you teach, it's what you emphasize.

The problem with new is you don't have time for the old ones.

It's too late for preparation when opportunity strikes.

Climb the mountain so you can see the world, not so the world can see you. Focus all your effort on what is in your power to control.

My assistants and I often would spend more time planning a practice than the actual practice itself
