From Alain de Botton's, "How Proust Can Change Your Life"
the following premise:
"There are few things humans are more dedicated to than unhappiness. Had we been placed on earth by a malign creator for the exclusive purpose of suffering, we would have good reason to congratulate ourselves on our enthusiastic response to the task. Reasons to be inconsolable abound: the frailty of our bodies, the fickleness of love, the insincerities of social life, the compromises of friendship, the deadening effects of habit. In the face of such persistent ills, we might naturally expect that no event would be awaited with greater anticipation than the moment of our own extinction."
