text: When joining an after school activity you get a chance to meet more people and make new friends. Students that have joined activities are more willing to talk in class and ultimately become more confident. It feels better when you know more people at or around your school. Extracurricular activities give you a chance to be more social. Which is good for you, allowing you to express yourself in ways that you might not have felt comfortable doing before because you didn't know anyone around you.
