A forest without diversity is like a library with only one book.

Three things you need: The ability to not give up something till it works， the ability to give up something that does not work， and the trust in other people to help you distinguish between the two.

晏子春秋

"We are all in the gutter, but some of us are looking at the stars."

如果你出生贫穷，那不是你的错。但如果你死时仍然贫穷，那就是你的错。
