"A teacher affects eternity; he can never tell, where his influence stops" — Henry Brooke Adams

If a man empties his purse into his head, no one can take it form him

I have never met a man so ignorant that I couldn't learn something from him

You learn to speak by speaking, to study by studying, to run by running, to work by working; in just the same way, you learn to love by loving.

All experience is an arch to build upon

Those that know, do. Those that understand, teach

It is impossible to open a book without learning something
