My hobby is photography. Currently, in my free time, I’m doing a long term photo project documenting life along a road that runs 500 miles through my state.
I’ll pack up some gear, spend an entire Saturday driving a portion of the road while stopping in small towns taking pictures of people, places, and things.
I’ve mapped out free camping spots along the way, so in the evening I just blow up an air mattress and sleep in my car. Then I just pack it all up and drive home Sunday so I can go to work on Monday.
Gets me out, keeps me occupied, and gives me time to be alone with my thoughts so I can clear my head.
I’m not saying this is what you should do, but similarly if you have any hobbies, think of ways you can do it in a different kind of context.
