Imagine what it would be like if we went through life never encountering an enemy, or any other obstacles for that matter, if from the cradle to the grave everyone we met pampered us, held us, hand fed us (soft bland food, easy to digest), amused us with funny faces and the occasional 'goo-goo' noise. If from infancy we were carried around in a basket (later on, perhaps on a litter), never encountering any challenge, never tested—in short, if everyone continued to treat us like a baby. That might sound good at first. For the first few months of life it might be appropriate. But if it persisted it could only result in one becoming a sort of gelatinous mass, a monstrosity really—with the mental and emotional development of veal. It's the very struggle of life that makes us who we are. And it is our enemies that test us, provide us with the resistance necessary for growth.
