And if I should see it as my duty to traipse off and explore new frontiers?

Human knowledge is not advanced if we don't dare to do the impossible once in a while. The human condition is not improved by living in grass huts and eking a living out of mud pits. It is only when we dare great things that we improve not just ourselves, but our people. The invention of the plow occured because somebody dared to think "What if" and then pursue it. The development of anti-biotics occured because someone dared to ask "why" and investigated it. The first settlers of north america arrived here because they wondered what was on the other side of that wonderous new land bridge that had opened up.

Duty is that which MUST be done, but it is not ALL that can be done.
