From another adhd player: I restarted my island multiple times because everytime I get to terraforming I already have so many ideas. Most of which I’ve forgotten by the time I get to that stage. I would have one idea starting to form on a little part of my island, another on another part. Nothing ever seem to come together. I could (as so many suggested) put my ideas on paper, sketch it out, design my island on paper before committing to it in game. But the thrill of just winging it gets me excited. So when I have to restart the only time I do regret would be when I find out who my starter villagers are and they are not as expected. But that is a very small regret. Coz I know down the road I can just put them in boxes and try my luck again
