The truly successful teacher is the one you will never need again.
If coffee didn't exist, somebody would have to invent it for me very soon.
If you keep groaning, please do it to a rythmn I can dance to.
Please don't believe everything you hear about me, regardless of how true it may be.
The greatest obstacle to discovering the truth is being convinced that you already know it.
Fortunately in my work there's always a choice: I can choose to do it willingly or unwillingly.
