Prince William

As I learned from growing up, you don't mess with your grandmother.

I hope I'm not a tourist attraction - I'm sure that they come here really because St. Andrews is just amazing, a beautiful place.

I've had lots of kids come up and ask for my autograph, I've had a grandmother stop me and ask me if I know a good place to buy underwear.

My grandmother certainly does not care for celebrity.

Being a small boy it's very daunting seeing the Queen around and not really quite knowing what to talk about.

It's my mother's engagement ring so I thought it was quite nice because obviously she's not going to be around to share any of the fun and excitement of it all - this was my way of keeping her close to it all.

There's been a lot of speculation about every single girl I'm with and it actually does quite irritate me after a while, more so because it's a complete pain for the girls.

People say it's not ambitious, but it is actually quite ambitious wanting to help people.

My relationship with my grandmother has gone from strength to strength. As a shy, younger man it could be harder to talk about weighty matters. It was: 'This is my grandmother who is the Queen, and these are serious historical subjects.'

I'm still trying to decide. It's a really difficult one because I really enjoy my time in the Air Force. And I'd love to continue it. But the pressures of my other life are building. And fighting them off or balancing the two of them has proven quite difficult.

My guiding principles in life are to be honest, genuine, thoughtful and caring.

It's like a rugby team. If you're picking for the World Cup final, you're picking experience with youth. Everything is better off having that balance and that mix. I think that, especially, goes for the monarchy as well.
