Everything in tennis is so neat and nice but boxing has sport down to its essence; it is very pure and I like that.

Give it everything you've got. Leave nothing out there.

Obviously you try to keep as much of your private life as private as you can.

I don't go out of my way to get noticed. When I'm in Scotland it's tough, because loads of people come up to me. They're always really polite. It's nice, it's fun and good to speak to people who aren't involved in tennis, but some have this habit of just staring at me and that makes me really self-conscious. I'd rather they came up and said hello.

I guess the closest I came was doing chores around the house to earn pocket money. My brother and I would have to do the washing up, cleaning around the house, walking my grandparents' dog, lots of things. We didn't get a huge amount but it was always enough to be able to walk down to the local shops and get some sweets.

I've always been pretty careful at keeping track of my spending, so using my debit card is often the easiest way of doing that.

We Scots have a fierce pride in the things we do that others can never appreciate. I am the British No. 1, but I would prefer to be the British No. 1 from Scotland every time.
