Oh shit, long time no see /vpwt/!
Haven't written much of my Kahili story, but might as well drop for those interested:
https://archiveofourown.org/works/29523903/TOTT: I always write chronologically, so when I start feeling burned out in the middle, I focus on what I'm trying to build to at the end. Think over ideas, maybe sketch an outline, etc. That usually makes me excited to bridge the gap and reach that point.
