<p>Can you write your other essays (the common app personal and the supplemental) about activities, even though there is already a "most meaningful" activity essay? Can you do this even if you write abuot activity X for the short essay and then activity Y for the personal one?</p>
<p>You can do whatever you want. Just make sure that you aren't repeating yourself, and that the personal essay says a lot about YOU individually, not just you the soccer player or you the political activist.</p>
<p>Is it wise to write the personal essay about a personal passion (for me, research). And by passion, I mean something I stay up till 5 AM doing just cuz I can't stop.</p>
