I notice that if you have the door to your office closed, you get more work done today and tomorrow, and you are more productive than most. But 10 years later somehow you don't know quite know what problems are worth working on; all the hard work you do is sort of tangential in importance. He who works with the door open gets all kinds of interruptions, but he also occasionally gets clues as to what the world is and what might be important.

We also believe in straight-talking, telling it as it is, using simple language that people understand, telling people about the downsides as well as the potential upsides, and even telling the bad news that no one wants to utter, like our lack of belief in the sustainability of the Icelandic financial sector that already we had months before the collapse hit us.

It’s easy to try to exaggerate the problems just to get more attention. So for me, it was very clear that the best way to deal with that was to do the best science that I was capable of doing.

That’s a very good question. I think I’m a very lazy writer and by that I mean that I do not battle, I don’t struggle too hard against it. If I have difficulties in the writing, I just go and do other things. I don’t feel a compulsion to write. Of course, when I start writing then it becomes a compulsive activity, because I’ve begun something and I want to continue, want to finish it. … I know there are other writers who sit down religiously every morning, they take their espresso, they put a clean sheet of paper there and they sit looking at that paper until they’ve finished or covered at least a number of those pages. No, I’m not like that. I have to be ready. It has to gestate it for quite a while and then it’s ready to burst forth.

Write slowly and by hand only about subjects that interest you. […] Develop craftsmanship through years of wide reading.
