Teach or be Taught

If we stop learning, we're dead.

Among the best ways to learn something is to teach it.

Those who can, do, those who can't teach. George Bernard Shaw.
One of the more stupider things ever said in life.

Teaching is a noble calling, up there with call waiting and the call of the wild.

Teaching is a noble calling. Tell Lord Gloucester that I'll be with him in a second.

Idle thoughts on teaching

With apologies to Samuel Johnson:

Depend upon it, sir, when a man knows he is to teach in a few hours, it concentrates his mind wonderfully.
