Cao Cao was a famous warlord during the Three Kingdoms Period in Chinese history. At one time, hist troops were camping uneasily, there were alarms throughout the day and the soldiers were too fearful to sleep as the night came.
Cao Cao told them
that he knew there were enemy troops nearby far outnumbering them,
that they had seen him outwit the enemy many times before in similar situations.
Finally he suggested that they "put their hearts at peace and have a good night's sleep" for the coming battles.

This is how I intend to sell my vision, my ideas, and my products.
