In my naïvety, I thought people who were in rock 'n' roll bands were great artists, and it was a huge shock to the system to realise that they weren't, that they didn't even aspire to be, really. Some of them did, maybe, but some of them, like Samson, were very frightened of the idea.

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.
