The whole problem with the world is that fools and fanatics are always so certain of themselves， and wiser people so full of doubts.
世界的整个问题在于愚蠢的人和狂热分子总是对自己如此确定，而聪明的人则充满疑虑。
The world is a book, and those who do not travel read only one page.
Optimize your generosity. No one on their deathbed has ever regretted giving too much away.
We don't impose our style; we discover the style that each project demands.
The only way to do great work is to love what you do.
永远不要停止学习，因为世界永远不会停止变化。
