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."

"You can't expect to be happy if you're surrounded by mess."

"Health and happiness - these are true wealth"

"How can you live like this? It's like a pigsty!"

"You're going to get sick living like this."
