The world still has secrets

• Many of the ideas we take for granted today were once unknown and unsuspected secrets.
• For contrarian thinking to be valuable, there must be secrets left to discover.
• It is important to distinguish between secrets and mysteries:
  • Secrets are difficult problems that can be solved with effort and ingenuity.
  • Mysteries are problems that are impossible to solve.
• We should focus our efforts on discovering secrets, not on trying to solve mysteries.
