Be gentle to all and stern with yourself.
Quality is not an act, it is a habit.
Only the educated are free.
Leap, and the net will appear.
Who seeks shall find.
Without hard work, nothing grows but weeds.
I can, therefore I am.
The dog that trots about finds a bone.
Know or listen to those who know.
Expect problems and eat them for breakfast.
Humor has historically been tied to the mores of the day. The Yellow Kid was predicated on what people thought was funny about the immigrant Irish. When you're different in a society, you're funny.
