i do a lot of other things that i'm guessing you don't expect a 'real' writer to do. for example, i'm rewriting my fanfiction as original fiction.
right now. at this moment.

whatever gets you to put words on the page is a good thing. you can worry later, once the work of creating something out of nothing is done. for me, posting directly to a professional blog, with all the associations it entails, is a bridge too far for my anxious mind, so i'll share it to the void of my favorite social media platform first.
