“Knowledge earns you power, character earns you respect.”
“Knowledge will give you power, but character respect.”
“Money earns interest; integrity earns respect.”
“You can demand courtesy but you have to earn respect.”
“People need self-respect, but self-respect must be earned -- it cannot be self-respect if it's not earned -- and the only way to earn anything is to achieve it in the face of the possibility of failing.”
“Let me give you a tip on a clue to men's characters: the man who damns money has obtained it dishonorably; the man who respects it has earned it.”
