世界很艰难，但你更强大。

To think is to confine yourself to a single thought that one day stands still like a star in the world's sky.

Perhaps one day you muster the courage, to make a clean breast of everything in the heart only ended up to let others see the joke, because they did not understand you to say what, also don't know why do you think things are so important, say, almost cried out. I think the worst thing in the world, than with full of heart and secret, but no one can tell, but no one can understand!

对这个世界有所助益是获得快乐的唯一途径。

出自先秦《荀子·性恶》引古语。不知儿子的为人，看看他的朋友就清楚了；不知国君是否贤明，看看他左右的大臣是什么德行就知道了。
