理性是，也应该只是激情的奴隶，永远不能假装具有其他职责，而只能用于服务和服从它们。
Reason is， and ought only to be the slave of the passions， and can never pretend to any other office than to serve and obey them.
永远不要满足于现状，始终追求更好。
译文：老天爷的心思猜不透，但做人的道理容易守住。
The best music comes from the heart.
I'm the reason you're alive, I'm the reason you survive.
The value of an idea lies in its practical consequences.
