When you are writing something that is going to be published in some form, it is very tempting to edit as you write. Many times as I write things that will be published I am tempted to do this. I am tempted because it feels like a shortcut and a timesaver, but it is just a way to make sure that what you write is bland and boring. It is also a great way to make sure you do not write very much because if you edit as you write, it'll stop you from putting words on the page. It'll stop the flow. Writing should always be a two-step process. First throw the words on the page as fast as possible. Then, come back later and fix it. That's how you create good stuff for your readers. It's also the best way to make sure that you keep putting words up on the page without impediment.
