Watching a woman spinning flaming swords to improvised synth drum music, I realized that the real deal involves cultivating healthy obsessions.
Not addictions or passing fancies, but a lifelong struggle to know as much about something (either specific or broad) as you can. This can also be spread around to a few different healthy obsessions, but certainly at least one.
"Talent" can be innate, but what seems to really show up is the obsession. It's the little things, the big things, and all the things in between in any given topic or category. The people who know this see this in other people. The people who know this well recognize it in everyone, to one degree or another. They see the obsession engine as much as the thing that's being obsessed upon, or the person themselves.
