Well, I just came off a 5 day exercise of gathering and organizing all my writing attempts and I realize that in the past 4 years I have started 15 novels, some of 3k words (so one chapter that I gave to one person to read who didn't like it) to grand 200k completed first drafts that never got rewritten. (200k is grand for me)
Before this 5 day collecting and dusting and sifting exercise in what I'd considered "computer clean-up" when I started, I was just idling/procrastinating away adding notes and ideas every now and again on Evernote and Onenote and building playlists on Spotify for characters when the mood struck. I'd lost actual writing motivation BIG time and the ONLY thing that changed, the catalyst, was a fanfic-writing friend of mine invited me to join a writers workshop where every meeting you'd present something new to the group, not really for criticism as to if it's good or bad but really and truly, focusing on progress.
Fanfic feedback was great for me because there were emails that would pop up with someone saying "I AM WAITING FOR THE NEXT CHAPTER. WRITE IT NOW! PLEASE AND THANKS" and that would motivate me, but with original novel fiction that just stay dead on my harddrive, or even worse, out on OneDrive unseen unless I look for it... i ended up with zero stimulus, zero momentum.
Self Motivation is very hard for me wrt writing. But I realize now that I may be shame motivated as well. Not the healthiest way, you'd think, but I had a psychiatry professor actual run through the merits of his "shame therapy" and it's not all bad. (opinion)
I can't not join the writing group, and I can't join and then have nothing to put in my progress report. The idea of that, the horror of that, has motivated me, and I wrote like 1.5 k this morning. I'm here on this site even. Don't know how long it'll last, but I'm just sharing what got me to write again after maybe 8 months of stagnation.
