Love is one of the most profound emotions known to human beings. There are many kinds of love, but most people seek its expression in a romantic relationship with a compatible partner. For some, romantic relationships are the most meaningful element of life, providing a source of deep fulfillment.
Anais Nin put it beautifully when she said, "Each friend represents a world in us, a world possibly not born until they arrive, and it is only by this meeting that a new world is born." Though some natural loners are happy without them, most of us depend greatly on the company of true friends.
Ah, happiness, that elusive state. Philosophers, theologians, psychologists, even economists, have long sought to define it, and since the 1990s, a whole branch of psychology—positive psychology—has been dedicated to pinning it down and propagating it.
