My dream replacement for full time work: study and make art (a hobby I have plateaued in); exercise; become a better software developer and data analyst (I'm a manager these days); work part time (very part time) on a couple businesses I am involved with - mostly in creative R&D. I've recently become aware of an "elite" engineering firm that looks far into the future to build original and innovative technologies for clients - I would focus similarly.
