An example of good writing would be anything by Kurt Vonnegut, Jr. My favorite quote comes from his book Mother Night: "We are what we pretend to be, so we must be careful about what we pretend to be." I enjoy his writing because it is satirical yet dark.
I am sure successful authors create some sort of outline or organization of their ideas before they begin writing in order to have some sort of focus.
Writing may come naturally to some people just like with any talent, such as sports, music or art. However, with
practice, knowledge and determination I am certain one can become a better writer.
