Well you have vocation and advocation someone once tole me
   (career counsellor) - at one time I was deciding between
   computers and a music career as two possibilities that were in
   the running at the time. College didn't work out (ran out of
   $$$). So, I kept music as a hobby and computers as the $$ maker.
   Worked out. I think it could've gone the other way as well. None
   of which were "dream careers" but I found that I could "follow
   my bliss" from within any place I found myself in.
