How many lessons there are and how little they are taken

Man comes from a drop of semen and leaves as a piece of dust. He doesn't know when he came and he doesn't know when he's leaving, yet he walks on the earth thinking he knows everything.
There is no nobility with bad manners.
A man's worth depends upon the nobility of his aspirations.
Blessed is he whose own faults keep him from seeing the faults of others.
