I took up writing and sharing what I learned and it turned out to be an intensive fun actvity for a whole year...I did what I always dreamt of writing, romance novels, technical books on AI, science fiction, books on sensitive topics like abortion, books on my convictions...in total I wrote a 100 books that quenched that childhood dream...another transition example is my brother who always loved pigeons as a kid, he started raising them recently and the passion came back full speed that he is now exporting exotic pigeons and loving it more than the money....you don't have to look far, look at what gave you a sense of purpose as a kid or at any point in your life and take time to rediscover yourself - don't worry if the whole world disagrees or it seems silly - its just for you.

No offense intended, but I wonder if finding a hobby would help you more than finding another job (even a part-time one).

A part-time job can reduce the burnout, but a real non-work pursuit gives the extra time somewhere meaningful to go.
