At 6 years old I was literally biking by the river or wandering in the woods with my friends after school for hours on end. Every day was an exciting adventure without any adult supervision, just random groups of 2-10 kids who would gather in the afternoon to play together. The rule was "home by dinner or there won't be any dinner for you". I never did any extracurricular activity, ever.
This did not prevent me from going to a great university in my country, get my master in Computer Engineering, graduating in the top 5% of my class, have a curriculum good enough to legally immigrate to the US, and working at several tech companies including FAANG, making high 6 figures now.
I would never give away those wonderful memories and early life experiences for some random extracurricular activity just to "stand out" later on, I do believe such freedom helped form my character to a much greater extent than any scripted activity would have.
