I did! I've started fasting, and currently clearing out the house so it's a start. And mentally, yes I do believe I'm improving in general. The rest depends on money, which I am currently saving up.
Probably just goldfish to be honest. We used to have an aquarium full of fish in it when I was younger, but we sold it because of how much maintenance it needed.
I might commission some art of my town and its villagers, which I would make my signature. That probably wouldn't be for at least a year after NH releases though.
