I'm in the business to push it. I'm not likely to be attracted to characters I've already done. I have to be almost frightened by the possibility of taking it on. Over the years I realise I must enjoy walking that edge, I keep doing it. It's why I like what I do. The only other job I've ever had that provides that time in the morning where you're going to work and you can't wait to get there and the sun's rising and you're moving toward something you look forward to getting up and doing every day was being a carpenter. And it was because you're doing something different every day.
