Perhaps, I should simply quote:

"He who cannot obey himself is commanded...The devotion of the greatest is to encounter risk and danger, and play dice for death...And life itself confided this secret to me: "Behold," it said, "I am that which must always overcome itself."...Indeed, the truth was not hit by him who shot at it with the word of the "will to existence": that will does not exist. For, what does not exist cannot will; but what is in existence, how could that still want existence? Only where there is life is there also will: not will to life but—thus I teach you—will to power... And whoever must be a creator in good and evil, verily, he must first be an annihilator and break values. Thus the highest evil belongs to the highest goodness: but this is creative."
