I've had the same problem at times. It's kind of a mental masturbation; adding more abstract structures and more higher order functions.
Need to strike a balance between Get Shit Done and leaving behind code that isn't a pain to maintain.
In fact, often the kind of abstractions I've created when I'm in that masturbatory mode described above, it turns out that the abstractions aren't worth it in the end because they're only used once, and it doesn't actually make the code cleaner or easier to maintain going forward!
Yes, that's my experience as well! I'll carefully design code so that it can be extended and then find out I need to extend it in an orthogonal way I hadn't imagined, and my "extensibility" completely gets in the way. I've eventually just settled on, "build something simple and extend it when needed."
