We know from daily life that we exist for other people first... - Albert Einstein

"Love is a better master than duty."

"The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed."

"No, this trick won't work... How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love?"

"Try not to become a man of success. Rather become a man of value."

"We know from daily life that we exist for other people first of all, for whose smiles and well-being our own happiness depends."
