I loved flying as much as I thought I would and continue to fly aircraft.

One day, people will be able to buy tickets to visit space.

I'm Chinese-American, of course, and so it's very interesting to see China actually launch their own astronauts, becoming the third nation, following the United States and Russia, to do so.

I think it's good to have competition. Now we have a third country that can launch astronauts, so it's good for all of us. It makes us a little bit more competitive and wanting to be the leader.

I hope that China will continue with space exploration. It would be logical to have international co-operation. I hope that it will come about and that I can be involved in it.

As commander I was responsible for the overall success of the mission, and so I had to know at least a little bit about everything.

Space is very unforgiving business

Tinkering is something we need to know how to do in order to keep something like the space station running. I am a tinkerer by nature.

My running ambition is to keep doing it until I'm way past the point where I have any business running. Just to keep doing it throughout my whole life—to stay fit and feel good.

Of course, you'll have to meet the physical and psychological demands. A space walk takes a lot of energy.

Without books, the world will be void.

Commitment is what gives life to convenant.

You are your greatest product and behind every book lies an author who wrote it.

Reformers have the idea that change can be achieved by brute sanity.

A girl came up to me in a bar and said she wanted to be my apple pie. I wish I'd said something cool, but I was stunned.

There's always a backlash in everything that you do, but it's not going to stop or change anything. And it's not only an issue in Hollywood.

Fear pounds on the door to our heart demanding to be let in. Joy is modest and often comes into our lives like a shy person entering a room; it can take a while to even notice it's there.

I'm not going to / let a little thing like the world stand in my way. / Why should I? I understand it / as much as I understand penguins / and I still go to the zoo.

I do play soccer, but it's exhausting in a way.

Each of us has much for which to be grateful if we will but pause and contemplate our blessings.
