<p>i will ignore the strange fight above and tell the OP what I’ve learned in high school and through the comments of my Harvard interviewer:</p>
<p>colleges appreciate one or two DEEP interests- ones you actually cared about and can speak passionately about. Being a swimming MVP, you may have already found one of your deep interests. My Harvard interviewer was very impressed by how strongly I felt about my musical and journalism endeavors and said it stood out that I really went after my real talents rather than dabbling in 30 different clubs/sports/etc.
Hope that helps.</p>
