I no longer write and then have a few quick edits then post. I tried that when I first started and it led to a lot of stress. Although, I'm in an adjustment period with writing and working out a complete story before posting. I find that my confidence in a story is lacking when I do this. Maybe because I picked a different type of story to begin and I should have just stayed with what I knew to ease myself into a new posting/writing strategy. Is the story I just completed different from what I usually write? Not really, it is still a romance... it is just that this one is more fast paced and dramatic, more soap-opera instead of linear. I started out really enjoying the writing and story process of it, but like everything as I got closer to the end the questions started and when those start, the motivation begins to plummet. What I'm getting at, is that some authors find it challenging to end a story and become overwhelmed. So much so that it becomes a minor anxiety and it leads to them not completing it, ever.. because they believe they just won't be happy with the finished product.
I'm will usually just have stories that I know I won't complete - deleted. I keep them on my computer just to be sure I'll not pick them up or do an extensive rewrite. (I have one of those in the works right now, but I've not touched in a month or so) Or at least hidden from reader view.
A lot of people come here for a lot of different reasons. A lot of them leave when those reasons are met outside of GA. People become published and are too busy. People are lonely and want to find like minded people to bounce ideas and talk to... then they find someone. People grow up and start their lives on a more significant level and doing so have a lot more demands on their time. - I'm suffering from that as well. I have three young children, I guess I'm waiting for the newlywed stage to wear off, I thought with children and a dog it would... but luckily we've held on to the butterflies and rainbows, and I'm in the process of moving again. Hopefully to my little oasis so I can get back to hobbies and work... I never thought I would miss having a job, but being a stay at home mother is more taxing, I have more respect for those stay at home parents than I ever have before.
I've said this before - sometimes if you wish for authors you like to stay and work you have to give them something to work for. Some motivation that will keep them going. Don't automatically assume that they are happy with the "likes" and "reviews" they receive and pop in and give them a review and a like or a PM or something. You never know how 'close' some of them are to hanging it all up because they're wondering if anyone is still interested as well.
