  • A good writer knows how to tell concisely tell the story without harming its validity

  • Humans have a propensity for kindness but tend to direct it towards their own “tribe” or community
  • Variation offers the best likelihood for species survival
  • Our evolution is not limitless – we are bound by the finite possibilities of the planet on which we live that interacts with our genes and bodies
  • People don’t just have one identity and oneself – our brain pulls from experiences based on the situation
