Ways to shorten the time needed for a fresh perspective?

[Asong4you]

We can work on a part in a song until we believe it sounds fantastic, and then especially after some sleep or being away from it for hours, when playing the song especially from its beginning and hearing the new "fantastic" part, wonder what the heck, why did we think "that" was right?

I wonder if you know of ways to shorten the time needed to get a fresh perspective?

(I wish I could simply run around the house, or go for a drive, or work on another song for a few minutes, etc., rather than having to be away from it for hours.)

Plus, I wonder what some of the top notch pros have said about this, and if any books have addressed this, too?

Well, somewhere out there in Neverwonderland are the parts of all the great songs that were actually part of the songs but which never made it to the final recordings..........
I wouldn't be surprized if just about every songwriter has found with some songs that when they put some distance between themselves and it, there were parts that made them wonder why they existed in the first place. I know I have.

I find if I listen to a song in the morning all the worst of it comes out in the first listen. Good time to assess what is good and what needs to be fixed. I've started to slow down my process so that I give it a morning listen (after each change) until I feel it is really a keeper.....
I can't think of a speedier way to do it....

Go do something that completely takes your mind off it. Go to dinner, watch a movie, etc.

Drink, Eat & Sleep, (in other words no real shortcut to replace nutition, rest, perspective and aural fatigue reduction).
