Paul Graham writes about things we Americans are good at and not so good at….

Americans are good at some things and bad at others. We’re good at making movies and software, and bad at making cars and cities. And I think we may be good at what we’re good at for the same reason we’re bad at what we’re bad at. We’re impatient. In America, if you want to do something, you don’t worry that it might come out badly, or upset delicate social balances, or that people might think you’re getting above yourself. If you want to do something, as Nike says, just do it.
This works well in some fields and badly in others. I suspect it works in movies and software because they’re both messy processes. “Systematic” is the last word I’d use to describe the way good programmers write software. Code is not something they assemble painstakingly after careful planning, like the pyramids. It’s something they plunge into, working fast and constantly changing their minds, like a charcoal sketch.

Graham makes some useful points.
