國家是理性的行為者，他們總是會(huì)按照自己的利益行事。
States are rational actors, and they will always act in their own self-interest.
People are unreasonable，illogical and self-centered；Love them anyway.If you are kind，people may accuse you of selfish，ulterior motives；Be kind anyway.If you are successful，you will win some false friends and some true enemies；Succeed anyway.The good you do today will be forgotten tomorrow；Do good anyway.If you are honest and frank，people may cheat you；Be honest and frank anyway.People favor under dogs but follow only topdogs.Fight for a few underdogs anyway.What you spend years building may be destroyed overnight；Build anyway.If you find serenity and happiness，they may be jealous；Be happy anyway.People really need help but may attack you if you do help them.Help people anyway.Give the world the best you have，And it may never be enough；Give the world the best you have anyway.You see，in the final analysis，it is between you and God；It is never between you and them anyway.
"Every book is a conversation between the writer and the reader."
追求幸福不是要一直感覺良好，而是要朝著有意義的目標(biāo)努力。
