Who needs NaNo when you have CYS contests?
Jokes aside, the one time I attempted Nano, I wrote about 30k words before giving up. I might be wrong, but sometimes it seems they advocate for 'speedwrite any random thing and edit it later' to reach the wordcount and it didn't feel like much of an accomplishment. Whereas, whenever I take part in CYS contests, I'm able to churn out around 100k words in a month so there's definitely a system I prefer lol.
But best of luck with Preptober and your NaNo entry! :)
