Personal Essay v Short Answer

<p>So in my personal essay (which I really like and don't particularly want to change) I wrote about my three most important extra curriculars (which happen to be extremely related)</p>

<p>Do you think its okay to write the common app short answer activity thing on one of the extra curriculars discussed in the personal essay as long as I address a different aspect of that activity?
Or do you think the two would be too similar?</p>
