Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing.

Experience is the teacher of all things.

Smartness runs in my family. When I went to school I was so smart my teacher was in my class for five years.

The greatest sign of success for a teacher... is to be able to say, 'The children are now working as if I did not exist.'

I'm glad I was a teacher.
