Not so sure having Fable spend millions of tokens psychoanalyzing me is the best thing to do on PTO in retrospect

It was a bit of a disjointed prompt bc i added stuff later but the key parts are - "workflow Read and analyze all of my tweets and tell me about what you learn about my psychology." then later "Be sure to also read my other writings (on my website, Substack, and in formal publications, e.g. as indexed on Google Scholar) for context on how to interpret the tweets." also provided API key for the X developer platform
