Zachary is an over-achiever: Deans list at UNL; 2nd degree Black Belt in Tae Kwon Do, taught himself the guitar because he thought it was cool and ended up playing in a band.  Wants to be a US Marshall  

Dakota is introspective, loves nature (especially horses and wolves).  He worked for a gourmet French chef last summer because he thought it would be interesting.  Doesn't know what he wants to be.
