<p>Yes, a sport is "just another" EC. But sports, especially if you play year-round, are demanding, excruciatingly physical, and didactic of more than just the sport itself. I know sports-essays are cliche, but presented correctly, sports can become amazing extra-curricular activities.</p>
<p>Also, you shouldn't plan on pigging out on EC's senior year. Just concentrate on what you have and do something amazing (Like having your own recital in a concert hall where you play piano and violin (at the same time, if you can manage)).</p>
