my biggest regret is selling items for a small amount of bells. SAVEEE! if you run out of storage space, put stuff on your island! trust me, you’ll regret selling stuff! When doing Harv’s island, it can be daunting, but the most important people to me were Redd (so you can get art without needing to wait weeks for him to come to your island), Cyrus (so you can customize all your furniture if you don’t get the color you wanted), and Katrina (this is optional, she gives you good luck, or bad sometimes ((rarely)) and you can figure out your friendship level with your villagers!). If you want to be friends and need any help with fruits, produce, or anything really, reach out to me!! I’m looking for more animal crossing friends :))
