text: Going out of you comfort zone is a good thing, doing this can create new friendships just by talking and being friendly towards others. Students won't judge what extracurricular activity you have chosen, they are most likely there because they like the same thing. Having multiple friend groups can lead you being more social and having a variety of different personalities all around you. Later on in life this could make you more confident in social activities such as presentations, meetings, interview, and making new friends. If you are not antisocial and see someone whos by them self go talk to them be friendly, you dont have to become friends but that interaction will give them a boost in confidence.
