Also, knowing what to build helps a lot too. Many of the most successful companies and projects didn't come about just because there was a good developer/programmer involved, but because they identified a market with interest in it and built what said market wanted/needed. A lot of people will just build stuff they find interesting/fun to build, but no one will care. What they will care about is whether it solves their problems, and they'll often go for a hacky, poorly done solution that does if need be.
