This type of interdependence is the greatest challenge to the maturity of individual and group functioning."

- Kurt Lewin

"If you want truly to understand something, try to change it."

- Kurt Lewin

"A successful individual typically sets his next goal somewhat but not too much above his last achievement. In this way he steadily raises his level of aspiration."
