Quote by Leon Festinger

"The mind tries to maintain consistency between its various cognitions."

"If a man is told he will dislike a new gadget, he will actually find his first experience with it more unpleasant than would otherwise be the case."

"Cognitive dissonance is when your actions don't match your beliefs."

"People tend to seek out information that confirms what they already believe."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
