Buddhist views on leadership
The Buddha ministered to all levels of society including Kings. On the occasion when King Pasenadi of Kosala lost in the battle and had to retreat to his capital at Savatthi the Buddha said


  "Victory breeds hatred.
  
  The defeated live in pain.
  
  Happily the peaceful live,
  
  Giving up victory and defeat."


I take this to be advise around ones attitude to winning and losing. If you live with an adversarial attitude then you will never be happy. If you believe that my win is your loss then whether you win or lose you will be in a painful mental state. Happiness lies with moving away from this false binary point of view.
