I do need my independence. I have to have that.

I drive a tiny Toyota iQ. I'm quite frugal and often cut my own hair.

I'm a bit frightened of the idea of a full facelift because, when you look in the mirror, you want to look like yourself.

All I wanted to do was put together one of the best home maths systems in the world, and that's what we've done. I've loved numbers since I was two or three, and I get really excited about them. Now, I'm allowing myself to get excited about things. If you're doing it for a TV network or any major corporation, you have to put a lid on it a little.

One day Mum saved up for this exciting new thing - a frozen chicken. She cooked it on the Sunday and we all sat around waiting for it, but there was a terrible smell from the kitchen. She didn't realise that the giblets were in a plastic bag inside it. We just ate vegetables and she cried and cried.

I cannot do the piece-of-talking-meat thing, the 'Here's your money, wear a pretty dress and take the cheque.' I'm not made that way. I have to be as good as I can be at whatever I do.

I'm very pleased how my children have turned out.
