Make war not love. War is much more profitable. The way to a Ferengi's heart is through his wallet. If you fail to do so bad things can happen to you. Hate letters are just a example trust only your true friends for they will be truthful to you.
Revenge is sweet but profit is sweeter.
All things come to those who wait, even Latinum. Fine print isn't so fine. Manipulation can be a Ferengi's greatest tool, and liability. Money is immortal. He who shares his profit, gains nothing but loss.
