Mixing writing with editing is an easy mistake for newbie writers to make, because many mainstream writing methods actually do encourage writers to edit as they write. So, a lot of writers who haven’t yet found their own unique rhythm as an artist follow this advice. And it does work for some. I personally know writers who can’t write any other way. However, if you are an intuitive writer—if you are an INFJ or INFP personality type, highly sensitive, or an empath—the chances are high that editing as you write is going to spell disaster for you.
What does editing as you write look like? Well, it might be that you write the first chapter or two of the novel that’s been swimming around in your head for a year, and then you immediately give those first couple of chapters to your friends for feedback. Or, it might be that you’re halfway through writing your book and then you join a critique group and you give them samples and sections to critique. It could be that you write only the very first sentence of your work, and then you immediately go back and begin crossing out words and rewriting it.
Whatever it looks like for you, the idea is basically the same. You write something and then you evaluate and judge it, and usually doubt it and then change it. If you’re an intuitive writer, you almost always feel worse after the process and much less like writing anything new at all. If anything, you probably feel like you want to crawl into a deep, dark hole.
