成功的关键在于坚持和努力。

The greatest danger is not that we will lose our way, but that we will become content with where we are.

译文：清贫的生活，对读书人来说，就是顺境；节俭的日子，对种田人来说，就是丰收的年岁。赏析：读书要耐得住寂寞。清贫的生活能排除浮华奢糜之事，否则只会扰乱身心与学业。节俭是良好的美德，也是人类生存之需要。如果平常俭约，有所积蓄，即使是收成很差，也能丰衣足食。假如不懂得节俭，泿费粮食，即使年年丰收，也会缺衣少食。

The true genius shudders at incompleteness — and usually prefers silence to saying something which is not everything it ought to be.

我认为能够自嘲是很重要的。
