Sorry to hear that you gave up. What was the novel about?
I took that, 'take a story you dislike, and re-write it to be something you like,' advice and since I loathe the "urban fantasy" (i.e edgy, supernatural romance novel) genre and just about everything in it I decided to write something about vampires.
What was the turning point for you to stop?
I finished and edited one draft, then re-wrote it and I needed some sort of feedback for the final draft because it was too long, but I was attached to pretty much everything in it. Finding an agent/publisher is impossible given who I am and the genre, and because I fucking suck at self-promotion (makes me feel cheap and gross as it always boils down to manipulating people) so I tried to get family to read it, or at least bits of it.
After a few years I realized none of them were actually going to.
Then I tried finding someone online. Associating with writers online very quickly made it clear that most of them have no fucking idea what they're doing. I legitimately wish I could find the threads because it was just a bunch of low-brow porn authors getting their Dunning-Kruger on, and no one was ever willing to do more than 'critique,' the odd out of context paragraph.
Basically I realized that like everything else in life I would have to finish it alone. I might one day, but to be honest I find the entire world of publishing and writing extremely alienating.
Similar sort of issue at Quora. Whether or not your content will be supported by Quora seems to hinge on your willingness to spout the correct politics. If you do that, then you can say and do anything with impunity. I literally once saw (and can screen-shot) a 'Top Writer,' advocating corrective sexual assault for people with the wrong politics, and yet she remains a top writer and the answer was never collapsed. Shit like that is par for the course.
That wouldn't be an issue in and of itself. The problem is the 'wrong,' people face a lot of hostility and bias. For example Quora knows there are off-site groups where power-users share content they want collapsed for political reasons. People have proven it. They don't care though. It clearly suits them. Not only is the culture there alienating in general but it's not something I can do anymore when no one has my back.
