My goals is not to become a billionaire, but to build something great, and have fun while doing it. I believe the chances for that are bigger in Silicon Valley than Norway. If I fail, I'll move back and enjoy the wealth and rain.
A story that may be of interest; I used to work for a company called Aker Solutions here in Scotland, which is Norwegian as you probably know. The owner of the company, Kjell Inge Rokke, played to your strengths in Norway right. You are a maritime nation; read oil, gas and seafood. So despite no college education, he went on to work in your country's main industries and now is one of the richest persons in the world.
Looking forward, hydrocarbons are harder than ever to find. You'd imagine that geologists and the oil companies they work for will need amazing software. Importantly, they will be able and willing to pay for it.
