Remember, if you ever need a helping hand, you'll find them at the end of each of your arms. As you grow older, you will discover that you have two hands, one for helping yourself, the other for helping others.
The aim of proof is to understand, not just to verify.
Life is not worth living if it is not subject to reexamination.
Life is like a song, with highs and lows, what matters is how you perform it.
