The highest form of wisdom is kindness

He whose wisdom exceeds his works, to what may he be likened? To a tree whose branches are numerous but whose roots are few. The wind comes along and uproots it and sweeps it down.

A quotation at the right moment is like bread to the famished

Make your books your companions

The day is short, the labor long, the workers are idle, and reward is great, and the Master is urgent

There is no pity for a man who moans about living in one town and does not move to another.
