Most people do just a few of the things on your list at a time. However, life is long, so you can alternate over time - e.g. at some point you can take a less demanding or part time job (or even be FIREd already) which opens up time for other aspects of life. Even then, you'll have to choose just a few that you focus on, but again, you can still alternate over time - say focus on studying humanities for a couple of years, then maybe later do art for a couple of years etc.
