lets children believe that being good is worth something . and reminds adults that being good is sometimes its own reward . <| sep |> I guess for me the thing that makes me feel dumb is that the very detailed world , cultures , languages in my head that i think about every day are actually useless . I don ' t play tabletop games , i don ' t use my world to set stories , when people ask me why i ' ve been making notes on the people and places , history geography , religion and science of a made up bunch of islands on a planet not too far from here i really don ' t have a response . the languages definitely get a weird response because developing a language completely over many years means that it ' s all stuck in your head . i could have spent this time becoming fluent in a real world language but instead i can speak 3 dialects and one archaic form of a language that nobody else speaks . pretty dumb waste of time .
