I guess it was the first time I really thought about leaving. I don't just mean Iron Maiden, I mean quitting music altogether. I just thought, 'Nothing is worth feeling like this for.' I began to feel like I was a piece of machinery, like I was part of the lighting rig.

I think the best way to find out about something is to try to do it to the max. A lot of people take up a hobby or sport and then find an excuse not to carry on with it. Once I start something, I won't stop until I'm as good at it as I'll ever be.

Engineering stimulates the mind. Kids get bored easily. They have got to get out and get their hands dirty: make things, dismantle things, fix things. When the schools can offer that, you'll have an engineer for life.
