Every man carries two bags about him, one in front and one behind, and both are full of faults. The bag in front contains his neighbors' faults, the one behind his own. Hence it is that men do not see their own faults, but never fail to see those of others.

Please all, and you will please none.

The quarrels of friends are the opportunities of foes.

Put your shoulder to the wheel.

Appearances may be deceiving.

No act of kindness, no matter how small, is ever wasted.

Enemies' promises were made to be broken.
