Most people here don't have a wide emotional range. It's just the type of people astronauts are, they're required to be level.

You're always under the microscope, and you don't know which mission you're going to get. It's a surprise.

When you're a little different than others, it takes a little more time to fit in. If you really want to be there, there are no ingredients you need other than effort, perseverance and teamwork.

A lot of people, I think, would love to see the earth from above, wear a spacesuit. Certainly, when I was a kid, I wanted to wear a spacesuit.

Definitely you don't become famous by doing something bad; that's a professional death sentence.

Some people will always be volunteers to explore, and it is, in my mind, a privilege.

Nobody is going anywhere in 10 years.

On the day a country decides not to invest a cent in innovation, discovery or exploration, that country decides to be a tributary to others.

The opportunities to become an astronaut in Canada were far and few.

I am definitely a little more nervous for my colleagues when I'm working at mission control than I am myself, on the shuttle.

Only love can inspire us to sacrifice.

Put off thy cares with thy clothes; so shall thy rest strengthen thy labour, and so shall thy labour sweeten thy rest.

We each need to find our own inspiration. Sometimes it is not easy.

Football coaches don't have real problems.

I mean, it really has a lot to do with who is actually physically doing a lot of talking. And we've just noticed that as we've evolved we're still making all the decisions from this, like, "cave."

I personally don't believe anything is impossible. With enough determination and effort, almost everything is possible.

Ditch the dream and be a doer.

If we were a primitive society, movie stars would be gods.

See how these Christians love one another.

My big struggle is how people can not care, erase, not remember.
