When I was growing up as a little girl and as a teenager, I loved designing and making dogs' clothes and wanting to be a fashion designer. I took art and ceramics. I loved dance.

I was thinking as a little girl growing up that I would be there. When I look at whether we can go to Mars, it's definitely something we can do.

In fourth grade, I was interested in all areas of science. I particularly loved learning about how the earth was created.

I stayed in the astronaut program until 1993. People ask me why I left. I thought I had a lot of things to contribute that would be difficult to do if I stayed. I thought I could have a stronger voice as an advocate for space exploration. So I ended up starting my own technology consulting company.

By innovating and investing in health technology, we believe that we can really change the future of health.

If you are identified with certain opinions and an ability to express them, and if you can build yourself an audience, a partisan fan base - measured through social media - then you are an official opinionator, monetizable through books, television contracts and the speaking circuit.

How do you convince somebody to host a stranger for the weekend? That's not a trivial thing. It's not something I think you can throw technology at, marketing at, or sales at. We threw design at it because that's all we knew, and in doing so, I feel like we brought a human touch to it, which is so needed.

We will explore the mysteries of science and harness the power of technology and innovation. We will realise the opportunities of the digital world. Our youth will learn more from - and with - each other.
