I find this part inspiring, regarding how to "respect the opportunity":

  Practically, what this means is to first do the work that is given to
  you. But once that's under control, to reach out into the vast Google
  network, to learn what's being planned and invented, to coalesce a
  clear image of the future, to give it shape through docs and demos, to
  find the leaders whose goals align with this image, and to sell the
  idea as persistently as you can.
