Albert Einstein:
The world is a dangerous place, not because of those who do evil, but because of those who look on and do nothing.

Al Franken:
Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from.

John Lennon:
You may say I'm a dreamer, but I'm not the only one, I hope someday you will join us, and the world will live as one.
