Don't sweat the petty things and don't pet the sweaty things.
George Carlin

Badness you can get easily, in quantity; the road is smooth, and it lies close by, But in front of excellence the immortal gods have put sweat, and long and steep is the way to it.
Hesiod

Never be bullied into silence. Never allow yourself to be made a victim. Accept no one's definition of your life; define yourself.
Harvey Fierstein
