“Happiness is not, except in very rare cases, something that drops into the mouth, like a ripe fruit, by the mere operation of fortunate circumstances. Most people are not rich; many people are not born good-natured; many people have uneasy passions which make a quiet and well-regulated life seem intolerably boring; health is a blessing which no one can be sure of preserving; marriage is not invariably a source of bliss. For all these reasons, happiness must be, for most men and women, an achievement rather than a gift…”  —Bertrand Russell, The Conquest of Happiness
