I believe that often when we write fresh new content, our thoughts creatively continue to “work” as the old expression suggests…as we “sleep on it.” This applies especially to creative writing or even just copywriting in general.
Try working on two or three different projects over a period of a few days. Don’t be in a big rush to finish something off too quickly. But give yourself the liberty to be your “creative best” over a period of time.
SEO Example: Try writing your keyword rich decriptions (the ones you might use for directory submission) over a period of 24 to 48 hours. Write and re-write the next day. Watch and see if the quality of your decriptions do not improve sharply so that you end up with a keyword rich description that still reads well to the reader.
