When one thinks of a "leader," traits that come to mind are decisive, resolute, and firm—as opposed to confused, doubtful, or uncertain.  The inimitable Warren Bennis begs to differ.  What's needed most in an era of accelerating complexity is the ability to be nimble, which includes:

• declaring forthrightly (when true!) that the answer is, "I don't know;"
• seeking other points of view;
• a willingness to abandon hitherto-defended positions, beliefs, or (in the context in which I write) practice areas, branch offices, or even clients; and lastly
• recognizing and acting on the invaluable insight that what's next is far more important than what's known.

My wife and I call this "permission to think out loud."   Next time you're faced with a seemingly momentous decision, take it for a spin.
