Explore! You may not realize it now, but high school isn’t just a rigorous chore where everything is planned out for you in advance. You have the opportunity to join dozens of clubs and extracurricular activities outside of the classroom.
See what clubs and activities are offered at your high school. Talk to some of your friends and classmates about clubs they're in and what they do. If anything sounds interesting or exciting to you, go to a few meetings. You might discover interests you didn’t even know you had and make new friends along the way.
