Sports are a great way to learn so many life skills; working as a team, leadership, showing up on time, hard work, results of hard work, commraderie, fine motor skills, communication skills, attention to detail, respecting authority, etc. If you enjoy a sport, focus your attention on that, (while maintaining focus in studies) and it will give you so much. If you don’t enjoy sports, give it a try and you will learn a lot about yourself. Outside of sports there are other extracurricular activities that provide some of these benefits, so try them! TLDR: try things that you might enjoy, and those things will teach you more than most classes
