“O sucesso não é a chave para a felicidade. A felicidade é a chave para o sucesso. Se você ama o que faz, será bem-sucedido.”

“Happiness is nothing more than good health and a bad memory.”

“Success is not the key to happiness. Happiness is the key to success.”

“Tranquil pleasures last the longest; we are not fitted to bear the burden of great joys.”

“Unquiet meals make ill digestions; therefore the happiness of a man's life is to be measured not by the great feasts, but by the frequency of his simple, pleasant repasts.”
