The mark of mediocrity is to look for precedent.
Every experiment, even the ones that fail, teaches you something valuable.
The reality is: sometimes you lose. And you're never too good to lose. You're never too big to lose. You're never too smart to lose. It happens.
翻译：懂得满足的人不会被利益束缚，注重内心修养的人，即便没有显赫地位也内心坦荡。
Why should you mind being wrong if someone can show you that you are？
