Philosophy changes day by day.

We are all made up of stars and all of us are billions of years old - that's what I believe, at least.

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.

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'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 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 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 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 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 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 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.

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.

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.

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

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

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.
