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.
Can you really claim to be into DIY if you don’t first mine the iron ore from the ground yourself?
I guess if you want to make a workbench, you first have to create the universe.
