One thing I learned from theater set construction is that you can slap some gaffer's tape and paint over any flaws, and the audience will never notice.
Except for others who do that type of work and so know what to look for. I have a friend who does trim work in mansions - I can't take him to a restaurant near me because the trim work is terrible and he can't help but stare at it the whole time - nobody else notices.
I went on a ferry ride with a friend who is a welder by trade and they spent a full hour examining the railings and critiquing the welding. It was pretty interesting.
Sounds like my dad (a former finish carpenter). He was never able to hold down a job because of his perfectionism. The union carpenters he worked with had a slogan: "If you can't see it from the freeway, nail it."
Reminds me of that typographer that specialises in historical typefaces and who according to their partner is insufferable when watching period movies as they point out all the fonts on the shops and set that wouldn’t have existed at the time.
