Those golden minutes before you are completely awake, when your mind is just drifting, you have no censorship; you are ready to develop any kind of idea. That's when I come up with the best and worst ideas. That is the privilege of being a writer - that you can stay in bed for an hour in the morning and it's work time.

All my friends who wanted to write had got nowhere trying to write the great European novel. So I deliberately steered clear of that and set out to write something story-led.

A rat is neither good nor evil. It does what a rat has to do.

I don't have any writing routine. Sometimes I go to my local coffee shop and I write there for some hours. Apart from that, I am traveling most of the time. I write in airports, trains, hotel rooms... I can write anywhere.

Until the Eighties, Oslo was a rather boring town, but it's changed a lot, and is now much more cosmopolitan. If I go downtown, I visit the harbour to see the tall ships and the ferries, and to admire the modern architecture such as the Opera House or the new Astrup Fearnley Museum on the water's edge.

A horse perceives eye contact as provocative, as if it and its status in the herd are not being respected. If it cannot avoid eye contact, it will react in a different way, by rebelling for example. In dressage you don't get anywhere by not showing respect, however superior your species might be. Any animal trainer can tell you that. In the mountains in Argentina there's a wild horse which will jump off the nearest precipice if any human tries to ride it.

I think I was righteous. I saw myself as the good guy in my own movie. I didn't get into many fights when I was younger, but when I did, they were righteous. I always thought I was defending something good. I fought for friends who couldn't fight for themselves. I was still being selfish and arrogant, but I was focused on what was fair and unfair.
