Oh wow, the coffee grounds thing totally reminds me of my grandma's old trick with eggshells! She used to crush them up and scatter them around her roses and swore the slugs hated crawling over the sharp bits. I tried it on my balcony last summer and honestly the slug damage did go down, though my neighbor said it was just the dry weather doing the work. Anyways the wild part is she also saved her bacon grease in a tin and poured a tiny bit at the base of her pepper plants, which sounds gross but those things went nuts. I never tried the coffee grounds myself but now I'm kinda tempted since my basil has been looking rough. The 6am watering tip makes a lot of sense too, I always watered at night and wondered why everything got spotty. Windy balconies are a whole different beast though, stuff dries out so fast up there.

Forget the walls, the mess under your desk is the only cable you actually have to look at every day. Those 4.7 miles are stapled inside studs and buried in insulation, so they might as well not exist. Your little pile of power strips and charging cords sits right where your feet go, and that tangles into a real problem. Tripping over a loose laptop cord or yanking your monitor plug out mid email is way worse than some hidden wires you will never touch. Why bother cleaning any of it when half the cables in your house are already lost to the drywall?
