If I really have nothing to do, I just watch my cats, take some photos, and go back to my personal blog.

As a human being, member of society, you must clearly state your mind. It's a responsibility. It is the way you identify yourself otherwise you don't know who you are and why you are here.

I think optimism is whether you are still exhilarated by life, whether you are curious, whether you still believe there is possibility.

The United States is a melting pot. Like John F. Kennedy said, it's a nation of immigrants. But Donald Trump wants to build a fence that clearly makes the statement: "You and I are divided. We're different, and you're dangerous." That kind of thinking stops human, civilized evolution. It's dangerous to create that kind of tension.

I think Donald Trump should cool down a little bit. To pay more attention to the history. To really understand what U.S.'s value is about. I think, as a president, those things you always have to ask.

I don’t want the next generation to fight the same fight as I did.

China partially wants to become part of the world. By hosting the Olympics and the Expo, they made a big effort to tell people: Look, we are the same. They want to be accepted by the international community.
