Good, Cheap Hobbies
What are some good, cheap hobbies to help be more productive? Any advice is welcome.

Most sports and exercise, reading, galleries, amateur dramatics, languages

I would say learning how to draw and sketching. All you need are pencil and paper

Exercise, like running can be pretty cheap. It’s a pain to start but it’s super rewarding if you stick with it

Listening to podcast, walks in local, state, or national parks, cooking

Gym, hiking, writing
