Joseph Conrad said this quote

A certain readiness to perish is not so very rare, but it is seldom that you meet men whose souls, steeled in the impenetrable armour of resolution, are ready to fight a losing battle to the last, the desire of peace waxes stronger as hope declines, till at last it conquers the very desire of life. Which of us here has not observed this, or maybe experienced something of that feeling in his own person - this extreme weariness of emotions, the vanity of effort, the yearning for rest?
