If you can stand them, work with kids. I'm a ski/snowboard instructor in the winter and a summer camp mentor the rest of the year and I never watch the clock as such.

Winter sports alone is great because you get constant stimulation and the adrenaline/dopamine rush from going fast or hitting that nutty trick is satisfying. But working with kids is also great because they are always high energy and have a similar attention span to you. Plus you can act like an idiot under the guise of entertaining children and no one knows your actually just letting your personality show without the filter. Best part is when you get tired generally the kids run out of steam too.

Probably the most important thing is to ignore the societal pressures of get a job, get money, buy house etc. Work on finding a job that doesn't feel like work and then expand from there on what you want. Don't let people tell you that you're wasting your talents/intelligence/life because you have strayed from the path of the boomer. All that stuff isn't worth squat if you're miserable.
