Attributes of effective leaders

While researching on the web about "Effective Leadership", I came across a site that listed attributes and skills that effective leaders possess.  The attributes listed were: perseverance, judgment, sensitivity, stress tolerance, self-motivation, ability to motivate others, educational values, decisiveness, relationship with others, intellectual capacity, and physical and mental energy.  The skills listed were: problem analysis, problem prevention, organizational ability, oral communication, written communication, and management by walking around.

What other attributes or skills do you think today's administrators need to possess?
