Quote by Walter Mischel

"The ability to delay gratification is a fundamental skill that predicts success in life."

"What you do is determined by what you think about."

"Self-control is the engine of human achievement."

"If you can wait, you can have what you want later."

"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."
