Five hallmarks of the great CEOs.

From the FT article by Robert Sutton ("Separating the best CEOs from the dolts")

1 They have what psychologist John Meacham calls "the attitude of wisdom"-the courage and confidence to act on what they believe, in concert with the humility and self-doubt.

2 Good bosses do not deny or gloss over their own weaknesses.

3 They devote seemingly compulsive attention to how others respond to their words and expressions.

4 They know how to lead and join a good fight. Good bosses "fight as if you are right, and listen as if you are wrong."

5 Regardless of how well their company is doing, good leaders keep challenging their assumptions.
