"Memory is the mother of all wisdom."

"The true art of memory is attention."

"We live in succession, in division, in parts, in particles. Meantime within man is the soul of the whole."

"Without repetition, nothing is learned."

"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."
