It sounds naughtier than the reality: Reading the manual, looking at what I've assembled, then swearing out loud for 5 mins, then telling myself "it's OK, it'll come out OK in the end"

And what do you know? It does come out looking good in the end (except for the IKEA cabinet, which has a weird gap where you can see the Blurays and whatnot, but I've drilled and pounded on enough wood.
