Quote by Cyril Burt

"Intelligence is inherited, but it's the environment that determines how it develops."

"The correlation between intelligence and environment is far more complex than we initially believed."

"Heredity and environment are not opposing forces; they work in concert."

"Psychology must be grounded in measurable data and rigorous statistical analysis."

"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."
