The only limit to our realization of tomorrow is our doubts of today.

The best way to be happy is to forgive.

Some birds is ultimately caged, because their feathers are just too bright, and when they fly away, you will sincerely congratulations>

形容人心难以捉摸，民众的行为像烟一样飘忽不定。

复杂性不仅仅是系统中组件的数量，而是它们相互作用的性质。

我们必须愿意失败，愿意犯错，愿意带着学到的教训重新开始。

The only way to be happy is to be true to yourself.

我不是一个喜欢和其他人一样的人。
