My world was completely different to other boys my age. When I was six I was earning money, and by 10 I was paying more tax than the parents of other pupils. I feel a lot older than my years. Because I was working with adults, I had to mature a lot quicker.

'Pulp Fiction' was probably one of the first films I ever saw that really kind of took effect on me. I was about four years old - obviously wasn't supposed to be seeing that film; my sister kind of sneaked it out and we got to see it. She's older than me. That was something I always used to watch.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.

Self-indulgence is something to watch, but anything that helps you understand situations that are difficult to understand is good. If you're having some sort of emotional trauma, you need to find a person to talk to about it who says, 'This is quite normal; it's fine.'
