“Man is fond of counting his troubles, but he does not count his joys.”

The darker the night, the brighter the stars.

The soul is healed by being with children.

Pain and suffering are always inevitable for a large intelligence and a deep heart.

Man only likes to count his troubles; he doesn't calculate his happiness.

The mystery of human existence lies not in just staying alive, but in finding something to live for.

Taking a new step, uttering a new word, is what people fear most.

It is not the brains that matter most, but that which guides them — character, heart, generous qualities, progressive ideas.

Pure mathematics is, in its way, the poetry of logical ideas.
