    4. make people feel like insiders -
  2. Triggers
    1. accessible thoughts and ideas lead to action (eg Kitkat and coffee break)
    2. forge a fresh link rather than link a product or idea that is already associated with many things
  3. Emotion
  4. focus on feelings; the underlying emotions that motivate people to action. Remember to pick ones that kindle the fire, activate people, and drive them to action
