What proves that you really got best results in editing as you mentioned it in your CV?

I believe that jotting something down on paper is not the final stage of writing andthat's why sometimes, in the quest for the perfect way to write something, a writer can get hung up on last-minute changes and revisions, ever in search of a sense of perfection.I have done editing in both Arabic and English for several media and advertising agencies as well as local newspapers and magazines.
