Problem with Common App/Stanford supplement

<p>For the "what matters to you and why" essay prompt, I ended up talking about being a mentor for underprivileged kids. This is also what I had originally planned to talk about in the Common App extracurricular short answer question, as it is the activity that I care about the most. Should I talk about my second most important activity (being president of a service club) so that I don't sound repetitive? Or should I try to further elaborate on being a mentor?</p>

<p>Second most important, they've already heard about it so it would be better to hear something new.</p>

<p>Yeah I agree, don't be repetitive, write about something else.</p>

<p>Understood, thanks to you both!</p>
