The people you already know in school can be a tool for expanding your connections. Start creating meaningful relationships with your classmates, teachers, club mates, and peers. If you find yourself struggling to meet different people, a simple act of introducing yourself to the person sitting next to you in class can help improve your confidence. This might require you to step out of your comfort zone, so take it slowly to begin with. You can also try moving around during the semester and taking different seats in the classroom.
