“You raise your voice when you should reinforce your argument.”
“Don't raise your voice, improve your argument."[Address at the Nelson Mandela Foundation in Houghton, Johannesburg, South Africa, 23 November 2004]”
“The volume of your voice does not increase the validity of your argument.”
“Let me tell you something: when you dance, you are the greatest dancer who has ever lived. And when you sing, you will have the courage to raise your voice to the heavens, knowing that you may never get an answer.”
“You can’t reject your sorrow, it always comes knocking when you least want it and it does bring enough reinforcements to wear you down.”
“Do your work, and I shall know you. Do your work, and you shall reinforce yourself.”
