I tried this for awhile, but was dissatisfied. I found myself a constant consumer of intellectual material instead of being an engaged participant. Once I realized that, I set course to become more of a producer of useful things. That's led me to woodworking, to running a consultancy, to producing AI/ML for nonprofits, and to writing academic works. All in all, I enjoy life substantially.
Years ago I realized that if I bluntly categorize the things I do with my free time into buckets of "productive" and "consumptive" it's the productive things that make me feel pretty great.
It’s also not exclusive. Different phases of life yield different productivity levels.
