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

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

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
