Cyber security is a dynamic space. The user faces different challenges every year because there are always new applications and data.

Journalism: an ability to meet the challenge of filling the space.

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.

Once boys' and men's challenges are clear, the question 'why now' quickly becomes 'why didn't we see this sooner?' The answer? Virtually every society that survived did so by socializing its sons to be disposable.

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.

Schools ought to teach students to challenge secular ideologies masquerading as science in the classroom.

Follow your curiosity, and have the courage to meet the challenge. That's where science starts, in my opinion.

Save for thee and thy lessons, man in society would everywhere sink into a sad compound of the fiend and the wild beast; and this fallen world would be as certainly a moral as a natural wilderness.

My favorite thing in the world is a quiz show, 'University Challenge,' so you can see what kind of sad person I am.

I challenge the idea that films about rich people are escapism and films about working class people are dour and sad. I find the opposite's the case.

I've seen plays that are, objectively, total messes that move me in ways that their tidier brethren do not. That's the romantic mystery of great theater. Translating this ineffability into printable prose is a challenge that can never be fully met.

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.

I've programmed myself musically to come up with love-feeling tracks that are romantic, sexy, but classy, all in one. And that's the challenge. Once I create that music, then the lyrical content starts to come - you know, the stories and things like that.

Woody Allen is really the ultimate. I love that he believed in himself enough to do what he did. And I have that same feeling - that there's nobody that looks like me in movies, nobody would cast me as a romantic lead, but I want to do it and I feel confident that I can.

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

In school you teach us not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not be greedy. Then why do you go out and do the things you tell us not to do? You grownups say you love us, but I challenge you, please, to make your actions reflect your words.

In this world filled with challenges, we do need help from time to time. Religion, eternal truth, and our missionaries are vital parts of that help.

Every new conversation, every new relationship, brings new challenges and opportunities for honest expression.

More than half of people who leave their jobs do so because of their relationship with their boss. Smart companies make certain their managers know how to balance being professional with being human. These are the bosses who celebrate an employee's success, empathize with those going through hard times, and challenge people, even when it hurts.

I want someone who can respectfully challenge me. I know what I believe, so there's no point in my taking on a relationship with someone who thinks like me or laughs at what I laugh at. I enjoy being with someone who can offer me the opposite.

We were all born with a certain degree of power. The key to success is discovering this innate power and using it daily to deal with whatever challenges come our way.

A vibrant civil society can challenge those in power by documenting corruption or uncovering activities like the murder of political enemies. In democracies, this function is mostly performed by the media, NGOs or opposition parties.

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.
