I'm a HS senior and I'm starting to think about filling out the Common App, so I have two questions. First, do I need to fill out all of the extracurricular slots? I only did four extracurriculars (ECs) but there are 10 available. I am applying to some top-20 schools so I don't want to hurt my chances by not doing enough ECs. Second, I don't have anything interesting to write about for the essays. Most other students I know have traveled or had surgery or something interesting and I'm just sitting home doing nothing. Is a boring life ok to write about in essays?
