I'm naturally athletic. I've been involved in sports since I could walk. So, for me to be sedentary is just unacceptable. Not only is it great for your physical body, but it gives me more energy during the day if I've worked out. I feel better. I look better.

My parents grew up during the space race, and I think they imagined the future would be us living on moon bases and everyone has rocket shoes.

During the dot-com days, one could take just about any company public and reap fortunes. All you had to do was to make sky-high projections for growth, say you were in the Internet space, and go along with unscrupulous investment bankers and their analysts.

There are so many women who contributed in a very real way in pushing for the space program during the time in which there was a lot of competition to get into space first, and to know that there were African-American women who were integral in that success is pretty phenomenal.

We may have a tacit understanding of how our solar system works, but watching the sun disappear behind the moon reminds us of the vastness of space and the enduring mysteries of the universe we inhabit.

The images of Earth's delicate biosphere, contrasting with the sterile moonscape where the astronauts left their footsteps, have become iconic for environmentalists: these may indeed be the Apollo programme's most enduring legacy.

During launch, the outside of the rocket is covered in a protective fairing, so we couldn't see outside, but as soon as that was jettisoned, my first view of the earth was over the Pacific Ocean, which was this wonderful deep blue, with clouds just over the top, and sunlight streaming in through the window.

The Constitution that I interpret and apply is not living, but dead, or as I prefer to call it, enduring. It means, today, not what current society, much less the court, thinks it ought to mean, but what it meant when it was adopted.

Yes, people used to recognise me even during the initial days of my career as I am an actor. But now they have started approaching me with a smile and share their happiness with me. This change is all because of my humorous roles.

Every year around Christmas and Thanksgiving, I buy a bunch of toys for the sick children in the oncology center at the St. Louis Children's Hospital. I really love giving back and putting a smile on their faces, especially during the holidays.

I'm kind of living a Bruce Wayne life and then morphing into Batman, but I'm glad now Batman comes out during the day. That's kind of like how drag was: we were called upon at night to make people smile and laugh and clap.

If you can't relax during your interview, then nothing you do to prepare will matter. Being yourself is essential to the selection process, and interviewers will feel it if you're too nervous. Showing fear or anxiety appears weak compared to a relaxed smile and genuine confidence.

For me, music makes my smile brighter during my workouts. It adds that extra something that motivates me to go further or work harder!

Always wear a smile sometime during the day - it makes you feel happier and look younger.

No, I like to wear as least amount of makeup as I can during my everyday life because I'm just all about keeping my skin healthy and hydrated and I love to laugh and have a great time and smile - that's when I feel the most pretty so I just want to make sure that I stay happy.

When I was in Philadelphia during the Depression in 1930 or '31, I got a very sad job as a night watchman in a garage. The cars in the garage had been abandoned by their owners, since they had lost their jobs and couldn't keep up the payments.

It takes a long time for a country to build a strong base in science, but only a short time to destroy it. Germany was a sad example. It was a world leader in the sciences for more than a century, until its science base was demolished during the Nazi era, and the country ceded its position to the United States.

I'm not a singer. In 'Bye Bye Birdie,' I think I was the sad girl who sits on the park bench during 'Put on a Happy Face.'

I read too many romance novels during my formative years. I have a penchant for romantic comedies. I understand why 'Romeo and Juliet' came to such a pass.

When I watch a romantic comedy, I feel like they're selling something that doesn't exist. Two beautiful, but extremely unpleasant, people are terrible to each other for an hour, accidentally kiss, then decide to like each other during an extremely vague montage. That isn't how people fall in love.

Why is she Mrs. C.J. Walker? It really was a matter of her trying to insist that people respect her, because during that time, white people would call any black woman 'Sally.' 'Aunt Sally.' So this was like... you can't call me that.

When I was in Cardiff, playing with the National Orchestra of Wales, they said they get letters from people complaining if they're smiling during the concert. Nuts, isn't it? As if you have to respect the solemnity of the music by not smiling. Music is this joyful thing that enriches our lives, and you're not supposed to smile?

Respect and consistency, as hard work during the week is the only way to earn your place.

People who supported Obama felt like they formed a relationship, that they were being spoken to. The way that campaign worked and the way he's worked during his first term is to make people feel like he's grasping their hand, whether it's by tweeting or email, moments after an event, sometimes during an event. It makes people relate to him.
