I love the level of detail ( probably, because I see it less and less these days ). It genuinely makes me wonder if anyone tried training LLMs on their own writings ( assuming those bigger than 100+ pages ) and what the results were.
/r/localllama every once in awhile has such posts; usually very succesful, good results.

I just want to chime in here about the importance of taking notes and having a journal. These things are now more important than ever as they can literally help fine-tune agents to help assist you using your personal style.
