"But the successes have their seamy side, especially when they are attained with comparative “ease” — “unexpectedly” so to speak. Such successes sometimes induce a spirit of vanity and conceit: “We can achieve anything!”, “There is nothing we can’t do!” People not infrequently become intoxicated by such successes; they become dizzy with success, loose all sense of proportion and the capacity to understand realities; they show a tendency to overrate their own strength and to underrate the strength of the enemy..."
-J. Stalin
