Those Swedish startups didn't form out of nothing. Not only was Sweden early when it comes to things like personal computers, internet access and English, but also notable in many other areas. Almost all successful Swedish companies are at least partly related to gaming, music or telecom. That stems from a rather long organic history of the demoscene, artists and industry. Attitude might have something to do with, but few people would say that the Swedish attitude is anything like what people commonly think is needed for entrepreneurship.
