“The reward for doing right is mostly an internal phenomenon: self-respect, dignity (self-worth), integrity, and self-esteem.”- Dr. Laura Schlessinger

What this quote is saying is that the most best reward of doing or having is have self-respect for yourself and dignity and other good things about yourself because that’s the best reward you can get. Because a person who does the right thing has dignity and self-respect, and integrity because they don’t expect to get something back they do it because they want to they have good self-esteem for their self.
