The art of communication is the language of leadership.

The art of leadership is saying no not saying yes. It is very easy to say yes.

Leadership is the art of getting someone else to do something you want done because he wants to do it.

I have for some time urged that a nuclear abolition summit to mark the effective end of the nuclear era be convened in Hiroshima and Nagasaki on the 70th anniversary of the bombings of those cities with the participation of national leaders and representatives of global civil society.

As a young black boy it made me proud to see black leaders that did something amazing and made the world change.

Half a century ago the amazing courage of Rosa Parks the visionary leadership of Martin Luther King and the inspirational actions of the civil rights movement led politicians to write equality into the law and make real the promise of America for all her citizens.

Outstanding leaders go out of their way to boost the self-esteem of their personnel. If people believe in themselves it's amazing what they can accomplish.

But no nation can base its survival and development on luck and prayers alone while its leadership fritters away every available opportunity for success and concrete achievement.

Leadership is the other side of the coin of loneliness and he who is a leader must always act alone. And acting alone accept everything alone.
