Your hobbies should bring you joy. There are too many things you must do on a day to day basis for a voluntarily pursuit to be a joyless affair. I stopped running and training for triathlons in 2020 during the pandemic. It did not bring me joy anymore. Once I had accomplished my goals with triathlons there was nothing driving me to run 15 miles a week. So I stopped. I still bike multiple times a week and I love it. The feeling of being on a bike is deeply satisfying to me. I hope that never changes.
