Better be wise by the misfortunes of others than by your own.
It is foolish to try to imitate the skills of others.
If you had half as much brains as you have beard, you would have looked before you leaped.
Others may try to feed our ego, but it is up to us to constrain it.
Love can tame the wildest.
In serving the wicked, expect no reward, and be thankful if you escape injury for your pains.
