Genghis Khan was a conquerer of Eastern Europe to Northeastern China, founder and first Great Khan of the Mongol Empire, and uniter of many nomadic tribes of Asia during the 12th century A.D.

Only one known work is written by Genghis Khan called Rules for Writers. In that writing, a historian lists 10 rules for writers (warriors). Those 10 rules are:

  1. Read like a writer
  2. Story
  3. Perform
  4. Main Points
  5. Character development
  6. Words are your warriors
  7. Structure
  8. Climax
  9. Edit history
  10. Act like a writer

In this quote, Genghis Khan is stating that everyone puts their self interest as upmost. For this reason, he is reminding readers to keep that in mind when trusting subordinates.
