The most important thing is to keep thinking, keep questioning.

处理世界复杂性的唯一方法是简化它。

预测未来的最好方法就是创造未来。

Literature is the most powerful antidote to dogma.

The best way to predict the future is to invent it.

You don't have to be a genius or a visionary or even a college graduate to be successful. You just need a framework and a dream.

I don't need a reason to be authentic.

Now I want to take this opportunity to give you some advice. Over the course of your life, you will find that things are not always fair, you will find that things happen to you that you do not deserve, and that are not always warranted, but you have to put your head down, and FIGHT! FIGHT! FIGHT! Never ever ever give up, things will work out just fine. Look at the way I've been treated lately, especially by the media. No politician in history, and I say this is great surety, has been treated worse, more unfairly. You can't let them get you down, you can't let the critics, and the naysayers get in the way of your dream. I guess that's why I won, thank you. I guess that's why we won. Adversity makes you stronger, don't give in, don't back down, and never stop doing what you know is right. Nothing worth doing, ever ever ever came easy, and the more righteous you fight, the more opposition that you will face. I've accomplished a tremendous amount, in a very short time as president.
