Keep smiling, because life is a beautiful thing and there's so much to smile about.

Love alone is the only reasonable activity or pursuit of humankind....For Love not only annihilates our fear of meaninglessness but empowers us to seek the happiness of others. And this indeed is our greatest happiness.

Seize the moment of happiness... love and be loved.

Every time you smile at someone, it is an action of love, a gift to that person, a beautiful thing.

If you want to live a happy life, tie it to a goal, not to people or things.

Life at its noblest leaves mere happiness far behind; and indeed cannot endure it. Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.
