如果一个人不过高地估计自己，他就会比他自己所估计的要高得多。

商业中唯一不变的就是变化。

A person may cause evil to others not only by his actions but by his inaction， and in either case， he is justly accountable to them for the injury.

Always demand a deadline. A deadline weeds out the extraneous and the ordinary. It prevents you from trying to make it perfect， so you have to make it different. Different is better.

我不与他人竞争，我与自己竞争。

I'm not a god, but I'm not a regular person either.

本当の幸せは、心の中にある。
