A person with all talents and virtues is called a "sage", a person with both talents and virtues is called a "fool", a person with perfect virtues is called a "gentleman", and a person with talents and virtues is called a "villain". Any technique to win over people will not make you a saint, but a gentleman will use it instead of making you a villain, and you will not mess with a fool.
