For my own work, I tend to think of it as letting the perfect be the enemy of the done. Because if I get locked into the perfectionism I never finish, and even if it isn't good, the next thing will usually be better for finishing this one.
If you should need a fiction writing teacher I could probably scare one up for you.
Yeah, that's a common pattern too. I'm going to focus them on non-fiction for now, but if there wind up being some who are more fiction writers, that's good to know. Thanks.
