Commit to your business. Believe in it more than anybody else.

The poor have no choice but to be honest. The rich can afford to be dishonest.

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.

我也没有像鸟禽一般地歌唱，我只静静地微笑，笑我自己幸福无涯。
