It's very selfish when I write. I'm not aware, ever, of writing for another person; I'm not even really aware of writing for myself.
You have to have something worth saying and then the ability to say it- writing's a double skill, really.
My very, very first professional job was when I was 19 years old - I got a job doing an educational industrial film on Shell Motor Oil's oil products. I really put my heart into it - I wrote a script for it, I did a lot of research.
