解释：本治则国家巩固，本乱则国家危亡。

If you want something you’ve never had, you must be willing to do something you’ve never done.

Love is the only sane and satisfactory answer to the problem of human existence.

Twenty years from now, you will be more disappointed by the things you didn’t do than the ones you did.So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover. （注：这句说话被部分人质疑不是由马克·吐温所说的。）
