how important are leadership positions?

<p>My grades are excellent and my courses pretty challenging. I'm just worried about not having any positions of "president" or anything.</p>

<p>Extracurriculars/Internships, etc:
- Field Biology Internship
- Sophomore Advisory Council of Student Union
- Layout Department of School Newspaper
- News Department of School Newspaper (My school newspaper annually receives an award from Columbia University for outstanding professionalism and adherence to journalistic integrity)
- About 125 hours of community service
- Arista National Honor Society</p>

<p>Should I try to get leadership positions, or is this substantial enough?</p>
