Did I have a mis-spent youth? I suppose I did in that I left school early without any qualifications, having bunked off a few times for tournaments.

The memories for the missed opportunities are stronger than for the ones I managed to get over the line in.

In all the years I've been playing, I've never considered changing my cue. It was the first cue I ever bought, aged 13, picked from a cabinet in a Dunfermline snooker centre just because I liked the Rex Williams signature on it. I saved £40 to buy it. It's a cheap bit of wood, and it's been the butt of other players' jokes for ages."

I could have had eight or nine world titles at least, and you do think about that at times.

If the money is right, I will fight a bear.

When I left Facebook, I left an enormous amount of equity on the table. I thought, 'I don't want to be a slave to money. I want to be a slave to something bigger: an ambition, a goal.'

I never really had the money to be a sneakerhead.

Both my parents were entrepreneurs and built a nice leisure business. But money was tight when I was growing up.
