Yes, I only signed up for 150k as well. I think it's doable without having to stress about it during the year. I only just hit my 300k target this year since I only wrote one long-it fic for spook_me and no others.
Definitely hoping to take some of the pressure off myself this year, though might take some mental retraining.
Here's to a hopefully fab 2022 (and we'll done you making it into the Tales of the Matrix Christmas edition!) :)
