Dear Mr. President,
亲爱的总统先生：
Congratulations on a remarkable run. Millions have placed their hopes in you, and all of us, regardless of party, should hope for expanded prosperity and security during your tenure.
向您此次非凡的竞选表示祝贺。成千上百万人对你寄予厚望，无论哪个党派，我们大家都希望美国的繁荣与安全在你的任期内得到扩大。
This is a unique office, without a clear blueprint for success, so I don't know that any advice from me will be particularly helpful. Still, let me offer a few reflections from the past 8 years.
这是一个独一无二的职位，没有一份明确的成功蓝图，所以我不知道什么样的建议会特别有帮助。不过，我可以提供我对过去8年的一点反思。
First, we've both been blessed, in different ways, with great good fortune. Not everyone is so lucky.
首先，我们都以不同的方式得到上天的眷顾。并不是每个人都有这样的幸运。
It's up to us to do everything we can (to) build more ladders of success for every child and family that's willing to work hard.
因此我们有责任竭尽所能，为每一个愿意勤奋工作的孩子和家庭建立更多通往成功的阶梯。
Second, American leadership in this world really is indispensable.
其次，美国对这个世界的领导的确是不可或缺的。
It's up to us, through action and example, to sustain the international order that's expanded steadily since the end of the Cold War, and upon which our own wealth and safety depend.
因此我们有责任通过行动和榜样维护冷战结束以来稳步发展的国际秩序，我们自身的财富与安全亦有赖于此。
Third, we are just temporary occupants of this office. That makes us guardians of those democratic institutions and traditions -- like rule of law, separation of powers, equal protection and civil liberties -- that our forebears fought and bled for.
第三，我们只是这个办公室的临时占有者。这令我们得以守护我们的祖先为之浴血奋斗的民主制度与传统--诸如法治、权力分立、平等保护与公民自由。
Regardless of the push and pull of daily politics, it's up to us to leave those instruments of our democracy at least as strong as we found them.
不管政治中司空见惯的相互掣肘，我们都有责任让这些民主的途径至少同最初之时一样强大。
And finally, take time, in the rush of events and responsibilities, for friends and family. They'll get you through the inevitable rough patches.
最后，在各种繁忙的活动与责任当中，要多陪伴朋友与家人。他们会帮你度过不可避免的艰难时期。
Michelle and I wish you and Melania the very best as you embark on this great adventure, and know that we stand ready to help in any ways which we can.
在你开始这次伟大的冒险之时，我和米歇尔向你和梅拉尼亚致以最美好的祝愿，我们会以任何方式尽可能地帮助你们。
Good luck and Godspeed, BO
祝好运，诸事顺利，贝拉克·奥巴马。
