I will listen to anyone's convictions, but pray keep your doubts to yourself.Johann Wolfgang von Goethe
If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart.Nelson Mandela
A good leader can engage in a debate frankly and thoroughly, knowing that at the end he and the other side must be closer, and thus emerge stronger. You don't have that idea when you are arrogant, superficial, and uninformed.Nelson Mandela
