New start?

Okay, so I finally made the decision to delete my old save data and restart my island completely. I did as much as I could on the island and was no longer excited to play. But I am definitely sad to see it go. It was one of my favorites in terms of island placement and villagers. Now I'm not quite sure what to do next. I was wondering if anyone had any advice on restarts or what they did to make things exciting again.
