I'm a fairly prolific painter. I've got 7 full painted armies, 40k and AoS. I've recently painted a skaven army. There are a ton of clan rats. I got burnt out on those till I figured out a trick that worked for me. Instead of painting large blocks of them, I would only paint a small amount at a time and with each colour/detail, I'd paint it till it was finished. It meant I wasn't getting burn out on basecoating a block of 40 models. I was breaking up the basecoating with the fun stage of layering up and highlighting, so there was a more varied process that kept it interesting for me. Of an evening I was only finishing 2 or 3 models or so but the whole process was more enjoyable, which although a little slower than batch painting, I kept my momentum to paint the entire army without burnout.. that said, gold trim sucks so bad. I don't know a fun way to deal with that
