Heh. I’m not in the trades, but ~15 years ago I decided to rock/tape/mud ~800sqft of my house myself… to top it off, my lighting design included wall grazing lights and a satin sheen finish and another wall that gets hit lengthwise for 10’ at sunset. That was a long, long period that tested my sanity and marriage. It was probably good enough after first pass, but my standards were far beyond unreasonable and I had to live with results.

I eventually got rather good, albeit slow, and now can easily finish a wall where you can’t find butt or tapered seams with a flashlight, with minimal sanding. It took many hundreds of hours over the years, and a clear idea of what the bar was, for me to get there. The results still bring me joy, but more also the intuition built up around working with mud translated to a quick ramp up for more ambitious projects with stucco and concrete.

Flat surfaces seem like such a modern obsession. I feel the attraction, but defiantly try to oppose the gravity.

At least you limited yourself to human scale hand-y work.

An engineer type can go down some dark yak holes trying to find solutions to achieve inhuman flatness

Id love to develop the skill for drywall, but then amount of mess and dust it creates is too much for me and my SO. Even if I did it off site, taking a shower and changing clothes every time is a hassle.
