Nietzsche considers the future as an event created when crossing the threshold between will and act

Let’s position ourselves, by contrast, at the end of this immense process, in the place where the tree at last yields its fruit, where society and the morality of custom finally bring to light the end for which they were simply the means: then we find, as the ripest fruit on that tree, the sovereign individual, something which resembles only itself, which has broken loose again from the morality of custom, the autonomous individual beyond morality (for “autonomous” and “moral” are mutually exclusive terms), in short, the human being who possesses his own independent and enduring will, who is entitled to make promises—and in him a consciousness quivering in every muscle, proud of what has finally been achieved and has become a living embodiment in him, a real consciousness of power and freedom, a feeling of completion for human beings generally. This man who has become free, who really is entitled to make promises, this master of free will, this sovereign—how is he not to realize the superiority he enjoys over everything which is not permitted to make a promise and make pledges on its own behalf, knowing how much trust, how much fear, and how much respect he creates—he “is worthy” of all three—and how, with this mastery over himself, he has necessarily been given in addition mastery over his circumstances, over nature, and over all less reliable creatures with a shorter will?
