Well, in a way it's a relief.* Once you accept that *most* of
  what you might think about will ultimately be unoriginal (which
  is a big blow to the ego) - then it frees you up to the
  challenge: Find something original. So I challenge everything I
  think is original. First, I enjoy the original idea.* I know
  I'll get that feeling of "a-ha!" "eureka!" and I let myself
  enjoy the sense of accomplishment. Then, I take on the
  challenge: I'm GOING to find someone else who did this already.
  When I do, then I act as if "I'm the boss". I think to myself,
  "Good, now YOU take care of it so *I don't have to!*" and then
  I'm free for a new original thought. A fully original thought is
  kind of scary when realize you have one.* I've done the
  research, I've checked, double-checked, triple-checked.* I
  exhaust all possibilities. Then..._what_? What do I do with it?*
  Am I wrong?* Then I start questioning my assumptions, poking at
  it from all sides, as if I was my harshest critic. I write down
  or remember all of the potential criticisms.* Then I know it's
  solid, good and bad and everything. But.. then what? Then it's
  marketing to let ppl know about it; explaining it... over and
  over again... or... just sitting on it, knowing I have something
  truly *original* ... but not knowing how to explain it to anyone
  else, because there's nothing else like it anywhere. It's kind
  of scary because no one can relate to it yet because it's new.*
  I've collected a few things like that and it's kind of awkward
  knowledge to have.
