Free online writing courses, writing workbooks: not helpful because I've read the theory many times over, and it appears that I know everything there's to know about the basics. What I really need is practice, but doing exercises without feedback and accountability is not motivating.
It should be useful to take a course where the homework is reviewed by the instructor, not by other students who may be equally clueless. But all such courses are way too expensive for me.
NaNoWriMo: not helpful anymore, because the novelty wore off, and the skills are not "transferable". There is abundant proof that quickly writing a lot of crap is a very different skill than slowly writing a readable story, and success in the 1st task does not help in any way to succeed in the 2nd task. (That is, for me, because my creative process is apparently different from those people who manage to edit their NaNoWriMo drafts into something useful.)
WriYe: the novelty wore off, and the forums are not helpful, because socializing is as difficult for me as writing. Forums and groups work best in an environment which prominently features a confrontation between "us" and "them", where "we" are united by common (imposed by "them") tasks and common dissatisfaction with "them". For example, "we" are players and "they" are the game company; "we" are students and "they" are course admins who do not handle the course well. Conflict is the driving force for successful socialization, just like for storytelling. When everything goes fine, it's boring. (But it shouldn't be too bad either, because then people will be under too much stress, and start leaving.) Back to WriYe, it's too loosely organized to have conflicts - there's no administration (besides the forum mods, but they're friendly), and all the tasks are self-imposed. All the challenges are optional, unlike MOOCs' homeworks. (MOOCs with no or optional homework do not work well for me either.)
Writing prompt communities with deadlines: somewhat motivating when they are active enough, but not too active, because wading through dozens of posts every week is overwhelming. Anyway, searching by "writing" as the interest, I couldn't find any suitable communities on DW. All communities I had the patience to check are either fanfic-specific, or roleplaying, or focusing on very short fics / drabbles, or dead, or void of content (there's one when you post your word count, and other users respond with congratulations, and nothing else is going on - what's the point of that??)
Writing challenges are motivating because they alleviate the sense of inadequacy I feel about my writing. This way, I (implicitly) say, "It's not my fault that this stupid story turned out so lousy, I was just following the instructions and I was pressed with time, do not take it seriously, it's just an exercise anyway." But it's a bit difficult to cheat myself into this frame of mind when the instructions are not externally imposed.
Accountability can be faked when the guidelines are very specific, like my 52 books in 12 weeks, and 50 games in an undetermined period of time, even though nobody gives a rat's ass if I succeed or fail. But this works with easy tasks. Usually I do have to make an effort with reading and even gaming (that's why they are challenges; I wouldn't care for a challenge of taking 50 naps in 25 weeks, or eating 50 steaks...) but writing requires more leverage.
The thinking continues...
