I think it depends on the family, the kid, and your priorities. We like to spend a lot of quiet time at home and aren't huge on rushing all around town every day, or even a few days a week.

My DS8 likes to spend time at home with us and isn't that interested in extracurricular activities, but we usually give him options every fall and spring to sign up for a class/program at our local rec center. This fall, he decided to do the swim class. He's a proficient swimmer, but wants to have all the levels signed off so he can be a lifeguard when he's in high school. We're thinking about a photography class in the spring.
