Frankly I don't know if it actually makes things more "effective" per se—the editing phase is the most difficult for me. I've collected some tricks to edit my own work (e.g., read out loud, change the font, triple space and print on paper, etc...) and also enlist the help of a friend, a peer, or a freelance editor. But this is where the doubts I had let go of come boomeranging back. By then though, the idea is usually strong enough for me to make a case for it and to keep refining. (If it's not I'll just shelf it and start on a different draft.)
