How many hobbies should a person have? I was thinking about this one day and I realized that I only have a few hobbies. I really enjoy playing tennis and video games and I used to practice martial arts, but I feel that it isn't enough and it means I'm a boring person. I feel this especially when I talk to other people who seemingly have tons of hobbies. So how many should a person really have? Do I have enough or do I need to shell out a couple hundred bucks and get more?
