Happiness, by its very nature, encourages trust, spontaneity, optimism, and enthusiasm — all of which bring great gifts. In particular, when you dare to be happy, you find that people instinctively gravitate to you and like you, although they may not know why. Maybe it’s something to do with your smile. Whatever it is, your happiness is an inspiration and a gift to everyone. Everyone benefits from true happiness . . . everyone benefits from your happiness.
