My guiding principles in life are to be honest, genuine, thoughtful and caring.
I think it's very important that you make your own decision about what you are. Therefore you're responsible for your actions, so you don't blame other people.
As I learned from growing up, you don't mess with your grandmother.
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.
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.
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 reasonably headstrong about what I believe in, and what I go for, and I've got fantastic people around me who give me great support and advice.
People say it's not ambitious, but it is actually quite ambitious wanting to help people.
My grandmother certainly does not care for celebrity.
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.
There are times where you can't do it yourself and the system takes over, or it's appropriate to do things differently. But I think driving your son and your wife away from hospital was really important to me.
I am and always will be an HRH. But out of personal choice I like to be called William because that is my name and I want people to call me William - for now.
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.
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.
I just want to go to university and have fun - I want to be an ordinary student. I'm only going to university. It's not like I'm getting married - though that's what it feels like sometimes.
