What does good writing have that bad writing doesn’t?
Good writing connects the writer and the reader. In really good writing, that connection between what the writer is trying to portray and what the reader sees is so tight that the reader will become immersed in the story and not let go until the last word is read and then will wish there was more.
Unfortunately, though writing is a craft that can be taught and learned, good writing goes beyond that craft and into something else. It becomes the art of the written word and that can’t be taught or learned except, perhaps, through time and experience.
