Feedback is the worst. How am I meant to improve without it? Not my problem!

I have recently hit a wall when writing new content. For the last few months, I have been looking back on my work, seeing it for what it is, and going "yep, i suck." I have been trying out different things to make it better, but am currently in the phase of self-doubt and considering abandoning ship.<br><br>I am someone who has no problem sharing their work with others. I have never been one to keep my work private, and I will happily give someone my work to read and critique. I am aware that I am not a good writer, and I am open to making the changes to better myself and my writing. The problem is how long it takes to get feedback out of people who I give the manuscript to. If I give a client eight hundred pages of a fantasy epic to read, it will take three months for them to get back to me with feedback. That's fine, I appreciate the hell out of them for lending a hand to a poor writer like myself.<br><br>The problem is that I have been making the adjustment of "I'll write one chapter, then edit that one chapter before moving on to the next." Suddenly, I am stuck in this loop of constantly editing the first four chapters of every manuscript I have, until I start a new one and get stuck in the same loop. It can take months, even years for me to go back and edit the entire thing.<br><br>I am a prolific writer. I can write about 50,000 words a month, but I can only edit about 10,000-20,000 per month. I have about twenty projects that I would like to complete. How the hell do I get feedback on my work quickly, if even my fastest beta-reader can only go through about 20,000 words per month? I have been struggling with this for years. I don't know how people are able to put out novels, completed and edited, this fast. It's unreal to me.
