Systems, yeah. Still, if you can maximize the overlap of systems
  I think you can find a greater level of satisfaction. I think
  the "find your life satisfaction through your career only" myth
  is somewhat of an annoying one that we're led to believe from a
  young age, at least in the USA... and I think can lead to a lot
  of misery. "Do what you love!" type of thing. At the same time,
  the point isn't a bad one: You can find aspects of your
  professional life that _also_ heal and feed your soul and also
  draw ideas from your professional life and bring them into your
  soul-feeding as well. In short, even if the systems don't
  perfectly map 1:1 with each other, there's bound to be overlaps
  that can strengthen both simultaneously, rather than seeing them
  as separate Universes altogether - although I think it's
  probably a pipe dream to believe that it's possible to have the
  two overlap 1:1 completely; just aspects.
