Not a nurse but I worked a lot of manual labor jobs that had me on my feet moving all day (e.g., home renovation work) and I can say that your body eventually gets used to that kind of work and the soreness becomes a persistent dull ache that honestly isn’t bad. Kinda like if you just work out daily.
Nursing may be different, and my experience may not apply, but I would think that you will get used to it.
Honestly the only thing I never got used to was standing in one place at retail work. Standing all day in the same spot is not natural and the body rejects it.
The wall is almost certainly already some variation of Swiss coffee, which is like a drop of black and two drops of umber per gallon… juuuuust enough to give it a little color.
When I used to help people pick colors the primary advice I gave them was that once it’s on the wall you will never see the difference between the four shades of [color] you’re looking at because at scale your brain blends it in with the lighting and ambient color of the rest of the room.
Sheen makes more of a difference, and the answer is always satin/eggshell for living spaces and gloss for kitchens and bathrooms (because it’s more moisture resistant and washable). Flat can go fuck itself, it only exists as a cheap option for track homes who don’t care about your paint looking good for more than six months.
