when im worldbuilding, i want to have reasonable explanations for why things happen so that itll be believeable for readers. however i feel i go overboard with it. i explain everything in a lot of detail because i cant be happy without explaining everything at least to myself, but then i get bored because its all too precise and scientific. how do i keep myself interested in worldbuilding? or, better still, how do i get myself to make it *less* scientific and more fun?
