What are your hobbies, /adv/? Which of them would you recommend

Ideally, you should keep hobbies that interest you. There are many hobbies with fringe benefits, but you'd likely find yourself dispassionate and uncommitted if they don't actually interest you, and it will show.

That being said, lifting and reading are extremely productive and useful hobbies. Add meditation to help improve your mind and at least one social hobby.

I pass the time by giving life advice to random strangers on an anonymous Internet image board. It's fun.
