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.

Until the Eighties, Oslo was a rather boring town, but it's changed a lot, and is now much more cosmopolitan.

But I tore ligaments in both knees, so I started studying business administration and economics and became a financial analyst, and I worked at a brokerage firm as a stockbroker.
