The only way to do great work is to love what you do.

没有情感，就不会有黑暗向光明、冷漠向活力的转变。

实现明天的唯一限制将是我们今天的疑虑。

"The role of the infinitely small in nature is infinitely large."

A method of solution is perfect if we can foresee from the start, and even prove, that following that method we shall attain our aim.

生活其实很简单，但我们坚持把它复杂化。
