Maintaining cheerfulness in the midst of a gloomy task, fraught with immeasurable responsibility, is no small feat; and yet what is needed more than cheerfulness? Nothing succeeds if prankishness has no part in it. Excess strength alone is the proof of strength. A revaluation of all values: this question mark, so black, so huge that it casts a shadow over the man who puts it down - such a destiny of a task compels one to run into the sunlight at every opportunity to shake off a heavy, all-too-heavy seriousness. Every means is proper to do this; every "case" is a case of luck. Especially, war. War has always been the great wisdom of all spirits who have become too introspective, too profound; even in a wound there is the power to heal.
