The most dangerous leadership myth is that leaders are born - that there is a genetic factor to leadership. This myth asserts that people simply either have certain charismatic qualities or not. That's nonsense; in fact, the opposite is true. Leaders are made rather than born.

Learning to be an effective leader is no different than learning to be an effective person. And that's the hard part

That is the key challenge facing management today; change is the only constant.

I'd always rather err on the side of openness. But there's a difference between optimum and maximum openness, and fixing that boundary is a judgment call. The art of leadership is knowing how much information you're going to pass on - to keep people motivated and to be as honest, as upfront, as you can. But, boy, there really are limits to that.

Make sure you have someone in your life from whom you can get reflective feedback.

Leaders are people who do the right thing; managers are people who do things right.

First and foremost, effective leaders must continuously strive to make themselves smarter and better at making judgments.
