General rules for beginners is one topic or idea per paragraph. But your "paragraph" is even harder to define as there isn't any real fluidity to it, it seems more like thoughts here and there in short sentences with little to zero continuation. I don't want to turn you off from writing and you should just keep on going in order to improve (no matter what people say), however learning from authors and books can also help along the way.
