text: Another thing after school activities are good for is interaction. It's sounds simple, but that's because it is. Simply interacting with other people in some sort of project can get you to collaborate with people you didn't know before. Depending on what you're doing, something you learn in an activity may become useful you later on. It could be an enlightening experience to help you in the future. Such activities also increase your socialization. This is good, especially for anybody participating that usually goes through things by themselves anyway. You can make a lot of friends and have great conversations if you take the time to talk to the new people you're working with, no matter what it is.
