I've done a lot of this as a writer. I'll actually take an article from a favorite writer of mine and paste it on the page. Then'll I'll go through that article and write my own article on top of it paragraph by paragraph. None of the content or subject matter is the same. I'm not "rewriting the original article". But it helps keep the patterns similar. I can see how I might want to change pace, structure the story, etc.

But even more importantly it helps me imagine being that other, successful, famous author.
