I knew from the age of 16 that I wanted to be a writer because I just didn't think I could do anything else. So I read and read and wrote short stories and dreamed of escape.

I thought, "Well, I'm writing about early childhood, so maybe it would make sense to write about late childhood as well, early adulthood." Those were my thoughts, and this was how this crazy book [Winter Journal] was composed. I've never seen a book with pictures like at the end, pictures related to things you've read before.

No one wants to be part of a fiction, and even less so if that fiction is real.

Money is the driving force of Hand to Mouth, the lack of money, and all those true stories about strange things in The Red Notebook, coincidences and unlikely events, surprise, the unexpected.

I've dealt with numbers all my life, of course, and after a while you begin to feel that each number has a personality of its own. A twelve is very different from a thirteen, for example. Twelve is upright, conscientious, intelligent, whereas thirteen is a loner, a shady character who won't think twice about breaking the law to get what he wants. Eleven is tough, an outdoorsman who likes tramping through woods and scaling mountains; ten is rather simpleminded, a bland figure who always does what he's told; nine is deep and mystical, a Buddha of contemplation.

All through my writing life I've had this impulse to write autobiographical works.

My children haven't read 'Winter Journal'. They have read some of my work, but I really don't foist it on them. I want them to be free to discover it in their own good time. I think reading an intimate memoir by your father - or an intimate autobiographical work, whatever we want to call this thing - you have to come at it at the right moment, so I'm certainly not foisting it upon them.
