Yes, this is indeed what I originally planned to do. Although I keep a book with the problems / ideas I have, none of them really motivates me (and I think there are about a hundred ideas in there). Given that there are enough ideas, I don't think the ideas are the problem...

I guess this is the perfect solution, but I don't feel like doing that now. I have the time, some money, lots of contacts and no car, expensive house or girlfriend. I have the ambition to become wildly successful. I've spend the last 5 years reading a lot on startups, but I don't see myself putting in long hours of software development at this moment.
