Another factor to weigh in the big decision whether to quit ("And this time, I mean it!") is whether you enjoy writing for itself rather than for publication.
I've been tempted to start a thread asking people why they're here, why they write, and what their goals are.
I personally just want to learn the technical aspects of writing so that I can do it properly. And by that I mean things like formatting, properly tagging dialog, etc.
There's also the aspect of getting to know what readers expect to see these days.
I grew up reading comic books, and a lot of old pulp fiction titles... The Shadow, Doc Savage, Justice Inc./The Avenger, and so on. And I can tell ya, many of those would NOT get published today. Between the repetitive descriptions, cliches, and general way they went from point "A" to point "Z" just wouldn't cut it.
And then there's Edgar Rice Burroughs, Robert E. Howard and L. Sprague de Camp... All favorites of mine that I'm pretty sure would get no traction today, at all.
The fact is, I have no real interest in being published, at this point. That may change eventually, but even if it does, I'm not someone who'll ever have a nervous breakdown over a rejection letter, since I write for me, not some agent, editor, or publisher that's only out to make money. Also, although I'll take the fortune, if it comes, I don't want a damn thing to do with FAME.
Anyway, I guess everyone has their own reason for anything they do, and I am curious about various people's reasons and expectations in writing and being here on the forums.
Finally, I will add that if a person is simply looking for a career... then maybe they do need to re-evaluate their ideas concerning writing, and their desire and aptitude for it.
Thanks for listening to me ramble. And Seth, I hope you find a comfortable and appropriate solution for YOU.
O.H.
