真知如同珍宝，不是轻易获得的，必须学习、钻研、思考，最重要的是必须有强烈的求知欲。It takes anyone to stand by your side at your best . But it takes a special one to stand by your side at your worst .
一个最困苦、最卑贱、最为命运所屈辱的人，只要还抱有希望，便无所怨惧。Thereis nothing more extraordinary than the power of nature. There is nothing more magical than the nature of nature.
A pessimist sees the difficulty in every opportunity. An optimist sees the opportunity in every difficulty .
No one can change a person， but someone can be a reason for that person to change.当我们憎恨某人时，我们恨的是这个人身上与自己相同的一部分，我们自己没有的部分也不会让我们讨厌。
