Quote by Francesco Petrarca

"Time is the substance I am made of."

"Nothing is so unbelievable that oratory cannot make it acceptable."

"Who is the happy man? He who has a healthy body, a resourceful mind, and a docile nature."

"Five enemies of peace inhabit with us: avarice, ambition, envy, anger, and pride."

"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."
