I notice that the quicker I put a track together, it usually ends up a bit messy melodically. It starts to sound like melodies being stacked on top of each other rather than multiple timbres working in unison for the betterment of the whole. During the production process, the producer is the most hyper aware of the track, so what may look like an empty project file may sound fine to someone who wasn't actually there to see it. But, whenever there's a little check mark to be filled in so to speak, I feel the need to fill it even if later, I realize it to be a detriment to the atmosphere of the track. When you listen to the same piece of audio over and over again ad nauseum, you're going to want to mix it up just for the sake of sanity in most cases - but this can easily end in a track that's far too short with too many transitions.
Recently whenever I've started really digging a track, I'll shut it off for a few hours and get my mind off of it. I'll come back to the track refreshed, and hopefully will have kind of forgotten what it sounded like at that point. I've found I've been a lot less impulsive when it comes to shoehorning in as much as possible.
