If I did that I'd be either an alcoholic, broke, or both by now! - 50 years of Engineering experience tells me "it just ain't worth getting your paddy up about". So you are right, walk away and shut the workshop door until your mind wanders to a different project - or come back another day after a good night of sleep.
I call it the "Round Tuit" principle - when my brain gets "round tuit" it will all work out as it should, but if I try and do it when my brain is all muxed-ip (or tired!) then I can drill square holes, cut curves with a straight blade, break anything supposedly "unbreakable" (especially taps and drills!), Bruise myself with hammers and spanners, etc., Upset my wife, cut a finger with a piece of paper, etc.
Music helps...
