Continual learning is key. Force yourself to see things from a
  perspective that makes you go, "NO WAY - THAT'S CAN'T BE
  RIGHT!!" - a perspective that you want to fight with EVERY FIBER
  OF YOUR BEING.

  THAT'S the perspective that will crack open your thinking
  processes into new arenas.

  You don't have to adopt it. But you HAVE to understand it _from
  their perspective_. Otherwise, you risk getting into locked
  thinking... the patterns fixed in the brain into predictable
  patterns... so predictable other people can see it from the
  outside.

  Of course, being unpredictable is a predictable pattern too*:P
