I never used to eat breakfast. I used to smoke 40 cigarettes a day and be running on adrenaline. From the time I left university and moved to London I became frenetic, like a hamster in a wheel. I'd thrown myself into running all these bars and nightclubs without ever pausing to reflect. But I got ill last year, totally exhausted, and it really scared me. Now I have bran flakes and fruit in the morning. I've started doing yoga and I've stopped smoking.

I usually dress very casually. Most of the stuff I wear is vintage American or Cuban. My grandfather is incredibly well dressed and I'm the same size as him, so he's given me some suits. When I first started working, I had my hair cut short, but it's grown back. My mum f---ing hates it.

I don't have a car - it's completely nonsensical to have one in London. I get the 23 bus to Oxford Street. That's my routine, day in, day out. I try to get to the office by eight. Quintessentially is a virtual club - members ask us to do anything from organising a holiday to getting first-night theatre tickets. When we started, two years ago, it was four of us in an office, round one computer. Now there are 40 of us, we have 2,500 UK members, and we've just launched a New York version.

The people we look after are often very demanding. Among the weirdest requests have been three snakes and a snake handler for a photo shoot, and a drum kit delivered to a boat during the Monaco Grand Prix. We booked someone into the Caprice yesterday and his car had run out of petrol - so we called the AA and got his car filled up while he was having dinner. If you need a taxi or flowers or a hotel, we do that for you. And we've created Essential British Culture, an arts club with monthly events with film directors, novelists, painters - people that we think are excellent.

My day is peppered with meetings about how to make our business better. I'm obsessive about details. Our clients are very frank with me - I get it in the ear hole if I'm not doing my job properly. When we started, people were pretty sceptical and rude about us. If I can take any pride in anything, it's that we're still here. The other concierge companies are more corporate - we take an individual approach. If you're into 18th-century oil paintings or bicycling in France, we try to come up with things that will be interesting to you.

At lunch time either I'm taken out by corporate people we're trying to work with, or I go for a juice and a wrap in Hanover Square. Because I'm quite hyperactive, I don't like sitting behind a desk, so I try and go for a walk to clear my head. The rest of my afternoon is taken up with thinking through things to do with the business. My father instilled in my sister and I that in order to enjoy ourselves, we have to have earned that beforehand. I don't think anything comes to people who just sit and wait for things to fall into their lap.

If I was just gallivanting around being a playboy, nothing would get done. It wasn't my 'pert bottom' pictured in the Sunday People and the Daily Mail last summer [both papers later apologised and settled out of court]. Being naked on a beach with somebody - I have no problem with that, but the article was saying I was a disgrace to my family, this wayward character. It upset my family and jeopardised contracts I was working on. Anybody who knows me knows I spend all my time working. That might make me dull, but it's what I do.

Sometimes I'll go straight from the office to dinner or to an event that we're involved in. On Mondays and Wednesdays I'll go to my ashtanga yoga class. If there's a midweek game at Tottenham, I'll go to that - I'm a huge Spurs fan. I used to play poker with friends at Aspinalls casino, but I haven't got the same love for it that I did. I don't feel I want to go and kill people at the poker table after yoga. But I love going to boxing fights, I love the theatre of it all.

Italian food is what I do best - but if I'm by myself I'll just have soup or something. Sometimes I fall asleep on the sofa watching TV. Or I'll get into bed and read a book. At the moment, because I'm tired, I sleep like a baby.
