Given a lever long enough, one can move the world with little force
-- MJ Engh
I thought it was Archimedes who said something to the effect of, "Give me a lever long enough and I will move the world."
Any way, some quotes that I have on my wall at home (without attribution since I forget who said them):
"Love has no expectations."
"When your thinking rises above concern for your welfare, wisdom independent of thought appears."
"Always make new mistakes."
