My mate Karl once told me he’d been looking after this five-year-old boy who – not knowing enough to have an ironic inflection to his words – said, ‘I want something.’ He didn’t know what it was. Not ‘I want sweets’, or ‘a can of Coke’, or ‘to watch the Tweenies’, or whatever it is they’re into now (I like Bagpuss), but ‘I want something.’ All of us, I think, have that feeling. And what heroin does when you first start taking it is tell you what that something is.

I think, you're not blagging me on this ridiculous journey, with this bit of paper. I think if you want to change things, it's not with an X on a piece of paper, it's with an X on someone's forehead.

Then, of course, through the umbilical link we all tumble backwards down the spiralling DNA staircase to one common ancestor in Africa, and before that some bunch of curious monkeys. Down and down we go unto the sea, unto the dust, the single cellular dust. What impulse drove one cell to become two? What yearning pulled the fish on to the land? What caused apes to walk upright? Some invisible magnetic pull. Is there a difference between attraction and intention? Where is evolution taking us?

Drugs and alcohol are not my problem, reality is my problem, drugs and alcohol are my solution.

When it comes to your career, you must always try and allow the positive aspects of your character to dictate what happens to you. Be led by your talent, not by your self-loathing; those other things you just have to manage.

We all need something to help us unwind at the end of the day. You might have a glass of wine, or a joint, or a big delicious blob of heroin to silence your silly brainbox of its witterings but there has to be some form of punctuation, or life just seems utterly relentless.
