So we'd say things like, let's agree that you're going to sell 57 widgets per week. If you sell them by Wednesday, please go to the beach. Don't create a problem for us, for manufacturing, for application, then we have to buy new companies, we have to buy our competitors, we have to do all kinds of things because you sold too many widgets. So go to the beach and start again on Monday.

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 how we are made as homo sapiens. We are biologically organized to cover distances on foot. That’s what we did for tens of thousands of years until we started to use horses, of course, until the mechanical age. And I would not call it “walking” because it’s not going out for a stroll or going out for a “power walk” or ambling in your city. It’s “traveling on foot.” You are reading the world, learning the essence of the world.

When you’re a carpenter making a beautiful chest of drawers, you’re not going to use a piece of plywood on the back, even though it faces the wall and nobody will ever see it. You’ll know it’s there, so you’re going to use a beautiful piece of wood on the back. For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through.

I've actually felt slightly uncomfortable at TED for the last two days, because there's a lot of vision going on, right? And I am not a visionary. I do not have a five-year plan. I'm an engineer. And I think it's really — I mean — I'm perfectly happy with all the people who are walking around and just staring at the clouds and looking at the stars and saying, “I want to go there.” But I'm looking at the ground, and I want to fix the pothole that's right in front of me before I fall in.

I mean, I still work alone. Really — I work alone in my house, often in my bathrobe. When a photographer shows up, I dress up, so I have clothes on. And that's how I've always worked.
