I look back at the looks I've had over the years. I'm proud of myself that I had the courage to experiment with crazy hairstyles and some fashion things. Would I do it again? No. But that's part of the learning process and getting from point A to point B.

Collaboration is just, really, a group of people getting in a room with their eye on a very similar prize and wanting to come out with the same show. The director, ultimately, is the guy in front of whom the buck stops. So, he has to have the courage to prevail. But, he has got to have a huge amount of respect for his collaborators.

I believe the biggest challenge is just getting the courage to try something different or new. Try to forget the stereotype in your mind. Yoga is for everyone - children, athletes, moms, dads, accountants, truck drivers, even country stars.

We had every problems starting a big top could have. The tent fell down on the first day. We had problems getting people into the shows. It was only with the courage and arrogance of youth that we survived.

Some people have a hard time getting rid of stuff. If that's you, pray for God to give you the courage to get rid of things you don't really need or things He wants you to give away. This will help keep your surroundings organized and clutter-free.

Every day begins with an act of courage and hope: getting out of bed.

Getting up and having the courage to share with people, all people, and even just being asked to sing, first of all, that's all part of how I express my identity.

Playing well with others is important - not being too flashy, just keeping good time and of course coming up with cool beats. A good snare drum, kick drum, high hat. Just getting good at the hand feet coordination.

I try not to name too many labels - not because it's not cool, but because it starts getting political.

Astronauts cannot pick their nicknames and can only get their nicknames from other astronauts. Any astronaut who tries to give himself a cool nickname will regret it by getting just the opposite from his astronaut friends.

As far as getting work, no one thought I spoke English. It was absolutely ridiculous. I'd show up at a meeting and they'd be like, 'Oh my God, you speak English! That's so cool.' They didn't really know what to do with me.

In recording, you're trying to make something work sonically - getting the right inflection on the right guitar sound - and maybe a part that would be musically great doesn't sound as cool. On paper, though, it's all stripped back. The musical idea is the one that wins.

A lot of people are focused on taking over the world or doing the biggest thing and getting the most users. I think part of making a difference and doing something cool is focusing intensely.

And getting stunt coordinator Dan Bradley and everybody from the whole 'Bourne Supremacy' crew, I think was real cool for our film because we do a bunch of really big jumps in this movie.

When I entered high school I was an A-student, but not for long. I wanted the fancy clothes. I wanted to hang out with the guys. I went from being an A-student to a B-student to a C-student, but I didn't care. I was getting the high fives and the low fives and the pats on the back. I was cool.

Getting past my early 20s, I feel a bit more maturity and responsibility about that stuff. You get a good feeling from doing something good. You see a kid and you make his day, you realise the power of it. Whereas before, I was like, 'That's cool, whatever.' But now, that's what I'm most appreciative of.

I write because it's my way of finding cool ideas, thinking through hard problems and things I don't understand, and getting better at something.

Rockets are cool. There's no getting around that.

I never cut class. I loved getting A's, I liked being smart. I liked being on time. I thought being smart is cooler than anything in the world.

It's so important to realize that every time you get upset, it drains your emotional energy. Losing your cool makes you tired. Getting angry a lot messes with your health.

Computers used to petrify me before I figured it was just a matter of getting used to them.

I like people writing great songs on guitar or piano or what have you. I miss people getting on stage with real bands and real instruments and expressing themselves that way instead of with computers and technology.

Young people, particularly in their teens and 20s, are not consuming sports the way my generation did. They are doing lots of things; they are multitasking. They are getting downloads; they are getting alerts on their computers or on their cellphones, and they are consuming sports in a more real-time but less full-time basis.

I used to have the very standard worldview. I can easily identify with people who see computers getting faster and smarter, and technology getting more and more beneficial, without seeing the other side.
