The notion that happiness and financial success tend to go hand in hand is, to my belief, true only to a certain extent. People with extremely low or high incomes tend to be least happy. An income sufficient to provide for economic security is most desirable for happiness: enough to make ends meet comfortably, with some left over to put aside, but not enough to put you in the wealthy class. Most people tend to be happier during that period in their lives when they are climbing the ladder of success, rather than after they have reached the top.
