I recently picked up a copy of the book "Relax, It's Only Uncertainty: Lead the Way When the Way Is Changing" by Hodgson and White and found it to be a terrific read.  It describes a set of skills called "enablers" which help one embrace ambiguity and uncertainty;  while another set of "anti-skills" called "disablers" are negative behavior patterns that get in the way.  A real leader should be able to embrace ambiguity - be able to admit it and deal with it.  The Enablers are

• Motivated by Mysteries
• Be Risk Tolerant
• Scan Ahead
• Tackle Tough Issues
• Create Excitement
• Be Flexible
• Be a Simplifier
• Be Focused

and the disablers are:

• Having trouble with transitions
• Not motivated by work
• Fear of conflict
• Muddy Thinking
• Complex communication
• Hooked on detail (Not everything that can be counted counts, and not everything that counts can be counted. - Einstein)
  
  •
• Narrow band thinking
• Tethered to the past

The book has interesting case studies on the above topics and some nice quotations as well.  Great read to understand leadership behavior.
