Sometimes you need to first write the words that you will later delete, to get through that part of writing and figure out which words are really needed. I often write knowing that it's probably just a placeholder for what needs to be there, or something I need to write out to have it clearer in my head but that doesn't need to really be there. Here's to hoping you either find it more useful than you thought, or that the right words will come to you at a suitable time!
