I kinda feel the same. Choose a field where you are already good and get a job/have a business in it for living. On other side become a ruthless learner of whatever you like. Go to different gathering of industries/disciplines, go to Expos,if feel like you can also join part-time university course or become a citizen scientist. Log your knowledge in any form of blog, journal, diary or personal knowledge-base. Hop between them when you feel like, if stuck read your past progress. It feeds my curiosity but it does not mostly create the positive cash-flow.
