In the past, I always used to be looking for answers. Today, I know there are only questions. So I just live.

Anything can happen to anyone at any time and you shouldn't just live through the days, or you lose them. You should do what you can to enjoy every moment.

I love a challenge and the last four years it has all come to fruition and it has been wonderful.

I can't be a wife. I'm not that sort of person. Wives have to compromise all the time.

I think I've probably re-invented myself three or four times now, if that's what one calls it.

I have a love-hate relationship with performing.

I am not quite sure where home is right now. I do have places in London and Milan, and a house in Spain. I guess I would say home is where my mother is, and she lives in Spain.

Being varied is something I do instinctively and naturally. I feel a tremendous sense of accomplishment.

In the past, I always used to be looking for answers. Today, I know there are only questions. So I just live.

You do have to be fairly selfish when you have a gift. You cannot afford to let too many outside things get in the way.

A journey into space is the greatest adventure I can imagine.

Apparently, everyone is most scared of the psychological tests. I didn't know how I'd fare. What I've found out is I may be creative and imaginative, but I'm also extremely together.

As I get older, I become more imaginative and feel like I have maybe a shorter time to get a lot of things going on in my mind done.

As I'm sure you may know, I'm planning to become a spaceflight participant and have been recently approved to begin my spaceflight training by the Russian space federation having passed the necessary medical and physical tests.

Everybody goes up and does something in the private sector that they feel that they can do, and obviously I'm a musician and feel that one of my experiments - because I think there are many that you can do and that you're helped with the ideas of what you could do - yes, would be to see how I would sing in zero gravity.

Finally my dream came true in that there was a possibility that I could travel to the International Space Station. I've gone through the medicals and the training and now I'm officially, by the Russian Space Federation, a cosmonaut in training.

I always felt older than my years, maybe because I was married to someone older.

I am an expert in the 'art of the possible.'

I am an interpreter of music rather than a composer of it.

I am not a composer of music; I sing pieces which have been written for me which gives me bigger freedom to search for pieces I want to record.

I can never say that I will never return to musical theatre. There may be a part in the future that I really want to do. I love plays as well. I am very open to ideas. I hope to do many things in the future.

I do quite a lot of flying in my concerts.

I don't force myself to exercise; I find going to gyms really boring. I find it easier to go for a fast walk or a jog in Central Park. I wear sensible shoes because my ballet dancing left me with a bunion on one foot after all the pointe exercises.

I don't think I would get married again; I don't know if I'm a very good candidate because of all the touring I do.

I feel a tremendous sense of accomplishment. Everything is in tune: the voice, the type of music, who I am and who people think I am.

I feel that people really feel they've got a part of me when they listen to my albums and the themes just show themselves.

I had been overexposed in a particular way because my marriage to an extremely successful older man meant I was involved in his public life as well as my own.

I have the sort of round face that you complain about when you're younger, but which serves you well as you get older.

I just wanted a change. My hair started hurting my back, so I went to my hairdresser and said 'Take it off.' And I'm delighted with the results.

I like, 'I Believe In Father Christmas' - that is one of my favorites it is a lovely composition; 'Colder Than Winter' as well. There are so many beautiful songs.

I look at composers and conductors, anybody involved in music or writing or art in general; they got more done as they got older. If I can, I'll be one of those people because what I do is my passion.

I love the intimacy of making movies. The focus is deeper and much more intense than musical theatre.

I never thought that I would be creating my own 'cross-over' genre. What I did was very real and organic. I have worked in so many different styles so it all just came together.

I think of myself not just as a dreamer, but as a dream chaser.

I think that it is always hard to find two voices that fit together well.

I was born in 1960, and space theory, especially in the last part of that time and going into the '70s, space was very relevant at that time. It was on television - all the experiments, the moon landings, everything like that.

I'm an interpreter of music.

I'm not flying to the moon. But when I've talked to people who have been up, you can tell it's really special because without fail a very special light comes into their eyes and they appear to be very fulfilled in some way and very calm.

I've always been interested in space and the idea of exploration in that area since I was a child growing up through the '60s.

I've always been involved with all aspects of my careers. Being behind the camera seems as natural as in front.

I've wanted to go to space, really, since I was a little girl.

It's in everyone's best interest to help close the gender gap in the sciences.

Life is too complex to compress into soundbites. Every situation is different.

Mozart is always a bit of a challenge - you know, even though it is often given to very young singers, it is actually the most complicated to sing in many instances.

Performing was something I could cling to. It was the only thing I had some control over and that's why I did it. If I hadn't, I'm not sure which way I'd have gone.

Philosophy changes day by day.

Right before I go on stage, I'm absolutely terrified. My mind darts at many directions, but the center of me is going forward into the performance.

The opportunity to orbit the Earth, witnessing multiple sunrises and sunsets every day, looking back to our small blue life-sustaining jewel from a distance, gives me the greatest sense of anticipation.

There is a reason that both have had the longevity in their careers that they have had. They have each done very different things throughout their careers and lived really interesting lives. There is a reason why they are up there still. After all, there is only one Barbra Streisand and one Liza Minnelli.
