I think it's important to make the difference between generic and intentionally designed. Just using an "abstraction" doesn't mean that your code is abstract, it may just not be a tangle of functions that were stringed together on the fly. At least for me, there's a clear point where I've coded something and find myself getting overwhelmed when making changes or trying to bridge the final gap to completion. That's when I step back and try to make sense of it and refactor.
