"The scope of economics is much wider than is commonly supposed."

"Human nature is the most wonderful and the most complex of all phenomena."

"The steadiest progress in the solution of a difficult problem comes from steady work."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
