Honestly, I take a deep breath, say Yes! And then, I set it aside.
No, I do. I set it aside wait about a week and then read it. After that, I send it to beta readers. Now why wouldn't I just send it out? Or read it immediately.
Well, that's simple. My brain needs to process the feeling of completion. I also don't like to send something to beta readers that hasn't had a read through. It seems unfair, and a little mean if they're going through and correcting all the typos I may have or fix sentences. So, I like to give them my best.
