Laetitiae Sanctae §7

⁷ A second evil, one which is specially pernicious, and one which, owing to the increasing mischief which it works among souls, we can never sufficiently deplore, is to be found in repugnance to suffering and eagerness to escape whatever is hard or painful to endure. The greater number are thus robbed of that peace and freedom of mind which remains the reward of those who do what is right undismayed by the perils or troubles to be met with in doing so. Rather do they dream of a chimeric civilization in which all that is unpleasant shall be removed, and all that is pleasant shall be supplied. By this passionate and unbridled desire of living a life of pleasure, the minds of men are weakened, and if they do not entirely succumb, they become demoralized and miserably cower and sink under the hardships of the battle of life.
