Being an astronaut is a wonderful career. I feel very privileged. But what I really hope for young people is that they find a career they're passionate about, something that's challenging and worthwhile.

The most important lesson of New Labour is this: Every time we made progress we did it by challenging the conventional wisdom.

Movie acting is a great job for your twenties: You travel all over, you have affairs with people, and you throw yourself into one part and then another. It gets more challenging as you get older, and it's not just having a daughter, it's wanting to have your own life and be yourself.

It definitely gets challenging at times. I travel a lot more now, and its never easy having to leave the kids, even if its for a few days.

Consider one possible future that could occur soon, where autonomous trucks travel highways with a human 'monitor' in the cab who can assist with particularly challenging driving like navigating city centres and ensure goods are delivered safely.

When you're a touring musician, you're always turning over new rocks, and there's always a certain level of tension in your life. The music business, and the travel that comes with it, is stressful, challenging, redundant, exhausting, exciting, and often very depressing.

I love to travel and to be inspired by new things, so everything is always new. I've never done the same bathroom or the same kitchen a second time. It's challenging, and I like to be challenged.

Enjoy your time in public service. It may well be one of the most interesting and challenging times of your life.

Making 'The Invitation' and waiting to make it on my terms and getting final cut and doing it the way I needed to do it was incredibly challenging, but it has really been so great for me. I'm so thankful that that's happened, that I got to work with actors I really like and have just such a good experience in delving into that story.

I'm just so lucky - my office is a racetrack. That is something I'm very thankful for. It's exciting, and it's challenging, and there are a lot of emotions and nerves that come with it, but right there before the gates open, before that minute and a half or two minutes of the race, it just hits you.

My parents made it clear that I should never display even the slightest disrespect to individuals who had the power to let me skip a half grade or move into more challenging classes. While it was all right for me to know more about a topic than my sixth-grade teacher had ever learned, questioning her facts could only lead to trouble.

Later in life, when my kids struggle to understand a tricky concept or master a new skill, I want them to have the strength and experience to tell themselves, 'I don't know how to do this... yet!' I want them to be confident that, even if something seems challenging today, they have what it takes to figure it out.

Just as the lunar landings inspired many young people to consider careers in space and related fields, the solution of the challenging instrumentation problems presented in space science can inspire young people to push beyond the current state of the art.

Ideologically, the pursuit of science is not that different from the ideology that goes into punk rock. The idea of challenging authority is consistent with what I have been taught as a scientist.

Acting can be pretty challenging. I can't say making a romantic comedy is challenging, but to do anything well, you have to put yourself into it.

Questlove is an artist who I respect because he constantly shifts within the idiom, challenging perceptions of hip-hop and black American culture.

I think to do anything out of one's comfort zone, there has to be some aspect of it that feels inspiring and challenging in a positive way.

I did this role in Life Goes On as an HIV positive character and so emotionally that was the most challenging.

It's easy to play a character who is suffering with a disease or has a psychological problem. 'Gentleman' is completely opposite. There are both positives and negatives in the role, and it is the most challenging role I have done so far.

We are constituted so that simple acts of kindness, such as giving to charity or expressing gratitude, have a positive effect on our long-term moods. The key to the happy life, it seems, is the good life: a life with sustained relationships, challenging work, and connections to community.

I've been called Mr. Patient Money because I have the patience to work through challenging circumstances.

I hate the idea of parenting being this false perfect picture. It's challenging and difficult at times. I like the fact I can be honest about that and people seem to respect that.

Parenting definitely has some challenging moments.

In my experience (I am the lone father of an eight-year-old boy who lost his mother when he was one year old), parenting is the most difficult of all jobs: forget your chief executives, editors, prime ministers and the like - parenting is far more challenging.
