Leadership for applying to college?

<p>Hi!
I'm starting to look at schools and I've noticed I don't have as much leadership ECs as I should. I volunteer a lot (animal shelter 4 years, just beginning work at area hospital, girl scouts, etc.), but being that I'm under 18 I can't hold many positions of leadership. I'm a junior so most clubs have presidents who are seniors. I run XC but I'm more of an introvert so I don't think I'd be voted captain... Any suggestions?</p>

<p>Most colleges care little about this…</p>
