Dennis Prager, author of the shrewd and perceptive
"Happiness is a Serious Problem," writes,

"There is a ‘secret to happiness,’" Prager writes, "and it is
gratitude. All happy people are grateful, and ungrateful people cannot be
happy. We tend to think that it is being unhappy that leads people to complain,
but it is truer to say that it is complaining that leads to people becoming
unhappy. Become grateful and you will become a much happier person."
