Teaching is the highest form of understanding.

So I find that teaching and the students keep life going, and I would never accept any position in which somebody has invented a happy situation for me where I don't have to teach. Never.

Good teaching is one-fourth preparation and three-fourths theatre.

Better than a thousand days of diligent study is one day with a great teacher.

Soap and education are not as sudden as a massacre, but they are more deadly in the long run.
