I'd like to see a series of example paragraphs, showing before/after a rewrite, to give me specific examples of how writing can be improved.
Is there anywhere that shows such things? I once read the biography of James Herriot, where they showed part of the first story he ever wrote, and you could see how poor it was compared to the final version eventually achieved.
I found this very intruging, and wondered if I could learn from more examples like that. So many changes cannot be explained easily, or defined by rules, and an example is needed to illustrate how things can be improved.
I spotted an example on this website just a moment ago too - the original example paragraph was slightly reworded in one of the answers: nameless-main-character
