I have thousands of words' worth of text that ended up not being turned into anything, and in a lot of cases it's because I simply didn't feel at the time like I could do justice to whatever I wanted to talk about and needed to do more research. but I rarely consider any piece of writing to be definitively abandoned. when that's been the case it's because after doing more research my opinions on something changed, or because enough time passed for me to have a different perspective, but I pretty much view all of my own drafts and notes and stuff I've already published as things to be cannibalized for future work
