I have been DIY-ing so long you’d think I would be good at it by now! I do buy some stuff pre-made (screws, electric drill, wire, etc) but I always think about whether I COULD have made it myself. When we bought our (premade) house in 2021, it had a few pieces of furniture, but I’ve made most of the rest (and you can definitely tell which is which!). I made my own computer (with some help from AMD and a few other “specialty suppliers”. I made my own off-grid utilities - something DIY almost every day. I’ll have to post a pic soon when something particularly “striking” comes along.
I do not aspire to make screws or wires, though there are those who do (and whether or not they are in their right mind, is certainly an interesting debate). But I regard them as things that have been artfully (if extremely rapidly) made, and I try to appreciate the convenience of NOT having to make them myself! :D (hey, no emojis?)
