My biggest motivation for building is that I can't build until I sell my damn island. Someone please buy my island; there's pictures and descriptions in a trading thread. Please someone buy my island I wanna start a new project ;(
I build because I don't want my island to be bland and boring. My main motivation is to make my island look good. It's also a lot of fun to build new things
I build cause uhm for a few reasons, it's fun and it's something to do alongside chatting with ya guys, uhm... I want my island to be complete like everyone else here and I want to make future mini-games that I have in mind and stuff and it would be a great place for some beacon/spawner hunts in the future
I build because I like seeing things progress, i've already spent a butt load of time building things but I always have new things i'd like to add in somewhere. Sometimes I don't feel the mood for it but there is mostly always something to be done to keep me busy.
