"I write to discover what I know."
That quote is by Flannery O'Connor. She spent most of her life in Milledgeville, GA about two and a half hours from where I live. I like many of her stories, though I have to read them in small batches as she is incredibly brutal to her characters.
I realize that writing a dissertation is not the same as writing a story or a novel. However, I think there is the same level of self-encouragement required to do it. I did some looking for a video or resources that might be helpful as you move ahead in this work. I found a couple that started with, "I haven't finished my dissertation yet, but..." I decided those might not be as helpful as I had hoped.
Instead, I'll give you the link to the National Center for Faculty Development and Diversity. If you're a Clemson student, you should have access to it through the university. If you're elsewhere, check and see if your institution provides it. I have found it to be very helpful beyond the dissertation as I need encouragement, suggestions, and ideas for how to structure my writing time. Here you go: https://www.facultydiversity.org
Finally, the photo below is one I took when we visited Flannery O'Connor's home - Andalusia Farm - a few months ago. I'm not sure that the pages were marked by Flannery O'Connor (particularly since Flannery O'Connor died about ten years before the first Post-It notes were on the market). Really the only reason I included this is to suggest that if this strategy is the only one you're using to make notes before you start writing your dissertation, that's not going to work.
