I write best to externally mandated deadlines, but I'm also thoroughly aware that I'm outside the norm in that. I can't even write to internally imposed deadlines well! It helps me a lot to know someone's waiting on it, which is why I do so many exchanges anymore.

Speaking of which, I'm aiming to roll my unfinished promptathon pieces into Yuletide/Secret Santa for timeline.

Congrats on accomplishing a Marvel Bang even in months. I've dropped out of every big bang I've tried because long novels haven't been my thing despite trying for years now, so I admire and respect those who can write sprawling works like that and finish them.
