It takes a smart man to know when he's stupid.
Barney Rubble
People think it must be fun to be a super genius, but they don't realize
how hard it is to put up with all the idiots in the world.
Calvin (of Calvin & Hobbes)
Great spirits have always encountered violent opposition from mediocre
minds. The latter cannot understand it when a man does not thoughtlessly submit
to hereditary prejudices but honestly and courageously uses his intelligence.
Albert Einstein
It's better to be silent and be thought a fool than to speak and remove
all doubt.
Abraham Lincoln
