I'm similar. I can overlook things if I'm distracted, and the overlook can be catastrophic for whatever it is that I am doing. Say I'm getting ready to catch a plane cross country to a attend a fancy event, I'll bring everything except my suit. Or if I'm fixing my car, I'll forget to put back an important part and have to redo the entire thing. I cannot do things while distracted, or I will mess up something major. Or even just parking my car, I will forget to put it in gear and it rolls out of the spot. If I'm reading something and getting distracted, my brain virtually dumps the entire thing and have to start over but with less energy.
For me it's not so much perfection that I'm striving for. If I tried my best, then I'm happy with the outcome. Instead I'm avoiding ruining the entire thing or making it worse. I have a very tough time recovering from avoidable mistakes, especially if they involve someone else, whether my mistake caused them harm or my mistake was because of them. I'm the epitome of an autistic kid losing their minds because someone messed up their things.
