Quote by William Stern

"The child is not a miniature adult, but a being in the process of development."

"Psychology must study the whole person in their total environment."

"Intelligence is not fixed but develops through interaction with the world."

"The mind grows through activity and experience."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
