Success is a lousy teacher. It seduces smart people into thinking they can't lose.

Come forth into the light of things, let nature be your teacher.

The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.

Technology is just a tool. In terms of getting the kids working together and motivating them, the teacher is the most important.

The object of teaching a child is to enable him to get along without his teacher.
