I think so. I beleive it is your current mission - THEY are your
  current mission. Their lives are intertwined with yours - if you
  can help them help themselves move forward in more and better
  positive directions, you have more than justified your existance
  on this planet, which of course needs no justification, but us
  "Helpers" do have that need. The little changes you help them
  help themselves make must be such an awesome feeling. "
