I think there are definitely two types of student: the academic kids and the 50% who fail. It's very clear to see - it's fact. We're not doing enough for those who fail; they need a more physical, tactile approach, involving people skills, team-building, problem-solving, building things.

Like most of the other teachers, I'd done a bit of teaching and we all think we're great at what we do, but you realize that normally you have an audience who are all onside, who all want to listen.

But I read Catching Fire. I loved disappearing into a story.

I hear loads of cynics saying that I'll never be able to change anything. They say that junk food marketing and the ready availability of fast food is just too powerful. But I'd say in response, screw you. I know that most people, if they're really honest, are fed up with the same old rubbish

40% of what I've done was a mistake. I now call it R&D.

Young people can be disruptive and screw up classes. But even if they are being a pain in the arse it's a cry for help - they don't feel like they are being listened to.

The whole idea is to earn the flavor. No one gives it to you.
