I think sometimes when it comes to sports, and especially relationships between players and coaches, that people lose track, lose a sense of reality.

I find interesting characters or lessons that resonate with people and sometimes I write about them in the sports pages, sometimes I write them in a column, sometimes in a novel, sometimes a play or sometimes in nonfiction. But at the core I always say to myself, 'Is there a story here? Is this something people want to read?'

It's long been a problem. But I'm not just talking about the UFC - I mean homophobia in sports in general and athletes sometimes say really stupid things.

Some of the authorities would like to remove rhythmic gymnastics from the list of Olympic sports and turn it into art. I think this would be wrong, as rhythmic gymnastics is a true sport - we train around six hours per day and sometimes spend entire days in the gym.

I don't read a lot of the sports, because I think people sometimes either build it up, or you have this guy that hates sports that is going to write bad about it, so I figure I'm not going to read it. Because I'm not going to let him put an idea into my head.

Sometimes emotions can win fights. Sometimes letting your feelings out in a fight can win you the fight. When it means the world to you, it's not just a sports contest - a boxing match for money or belts.

It's one of those things, like in sports and other situations in life, you're going to have some adversities and some challenges that are similar to the race. You go uphill one moment and then you go downhill, but that's life too. You've got to be willing to sometimes take it slow but keep going.

Sometimes in football you have to score goals.

Football is an incredible game. Sometimes it's so incredible, it's unbelievable.

I sometimes think this is just my life: I go to mow the lawn and sometimes go to space. But when other people say what you've done is really impactful, that's really humbling.

If I got the option of going into outer space and hanging out there for a day and then coming back home and dying the next day, or just waiting around to see if there's any opportunity for the technology to develop so that I might experience outer space sometime in the future, I would probably take the ride today and die tomorrow.

Sometimes we focus too much on our differences, but when we all look up into space, we see the same stars and we see the same sun. It really can be unifying.

Juggling is sometimes called the art of controlling patterns, controlling patterns in time and space.

Sometimes, properties of a fixed hyperbolic surface can be better understood by studying the moduli space that parameterises all hyperbolic structures on a given topological surface.

No one goes on a direct path, even though it sometimes feels like your peers might be racing ahead. Everyone's trying to figure it out. But if you just put yourself out there, step out of your comfort zone, establish yourself in terms of skills, mentorship, but leave space for your passions, then you're going to turn out pretty well.

Sometimes people ask me how difficult the astronaut program was, but being in Sierra Leone, being responsible for the health of more than 200 people, seven days a week, 24 hours a day, 365 days a year, at age 26 - that prepared me to take on a lot of different challenges.

Sometimes people wonder why aeroplanes are so cheap and rockets are so expensive. Even the most superficial comparison shows one obvious difference: aeroplane engines use outside air to burn their fuel, while rockets have to carry their own oxidisers along.

Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.

The negative side of football. The negative side of our society. People sometimes go to football and bring to it the negative aspects of our society.

I don't know why, but audiences are often sympathetic to thieves. Sometimes they are more sympathetic to thieves then they are to earnest people. What does that say about society?

The gift of loneliness is sometimes a radical vision of society or one's people that has not previously been taken into account.

I feel like sometimes that I was not meant for this society.

It doesn't all have to be about giving money. Sometimes it's a smile that changes the life of one little kid.

Sometimes, a nice smile can make up for anything, like when you can't get into an outfit comfortably.
