Klug & Faul =)
“"Ich unterscheide vier Arten. Es gibt kluge, fleißige, dumme und faule Offiziere. Meist treffen zwei Eigenschaften zusammen. Die einen sind klug und fleißig, die müssen in den Generalstab. Die nächsten sind dumm und faul; sie machen in jeder Armee 90% aus und sind für
Routineaufgaben geeignet. Wer klug ist und gleichzeitig faul, qualifiziert sich für die höchsten Führungsaufgaben, denn er bringt
die geistige Klarheit und die Nervenstärke für schwere Entscheidungen mit. Hüten muss man sich vor dem, der gleichzeitig dumm und fleißig
ist; dem darf man keine Verantwortung übertragen, denn er wird immer nur Unheil anrichten."
