" Anxiety is there. It is only sleeping. Its breath quivers perpetually through Dasein, only slightly in those who are jittery, imperceptibly in the 'Oh, yes' and the 'Oh, no' of men of affairs; but most readily in the reserved, and most assuredly in those who are basically daring. But those daring ones sustained by that on which they expend themselves—in order thus to preserve the ultimate grandeur of existence. "
