Hmm that's a good question. I am thinking about some ideas on using NLP to analyse my notes and create some kind of Dashboard of understanding with embeddings showing insights on how I think about things. The other thing I think could be interesting is for planning, like have a model that learns your routine and plans out the best course of actions, minimizing for some objective function that describes something like procrastination of some other metric that is easy to track and translates well to productivity and focus.
