Virtue is in the Balance Between Extremes

Virtue is in the balance between extremes. Between the insecure and the egomaniac: confidence. Between the uptight and the clown: grace. Between the coward and the daredevil: courage. Between selfishness and sacrifice: generosity. - Derek Sivers

A few other balances I can think of:

• Between the crowd and the lone wolf: charisma.
• Between logic and emotion: creativity.
• Between content and ambition: self-actualization.
