I think one key problem is whey people attempt to DRY the code before actually understanding what they're building. I like to let the code "tell me what to do"; I'm building something, and I repeat the pattern a few times, so I keep an eye on it. Eventually, I'll have a few repeated patterns I can look at. A lot of times, they're similar, but not the same. Waiting gives me the opportunity to review several similar patterns and find a more elegant solution that can accommodate all of the use cases, rather than forcing a sub-optimal abstraction for the sake of being DRY alone.
