Decide upon your major definite purpose in life and then organize all your activities around it.

我不是为了金钱或名声打球，而是为了热爱。

On pivoting: "If you're not stubborn， you'll give up on experiments too soon. And if you're not flexible， you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve."

出自《论语·述而》。通过不正当的手段，去获得名利地位，对于我来说，就像是浮云一样。
