agreed, "howl it"...i think allan ginsberg was a fan of this lifestyle too.
i'd say the yes to life goes hand in hand with the eternal recurrance. to quote will to power, "my dionysus world of the eternally self creating, the eternally self-destroying, the mystery world and the two-fold volumptuous delight, my "beyond good and evil," without goal, unless the joy of the cirlce (of life) is itself a goal." nothing is excluded in this view, nothing wished away. mistakes can be good in the end in that they have taught, if and only if, society is willing to learn.
about making mistakes. nietzche probably wouldnt call anything a mistake in the brood scheme of it all. mistakes for him only exist through the looking glass of moors and stigmas. he's a fatalist, "amor fati" is his war dance cry. he even reveres the mistakes of religions in that they give him an enemy to fight against. but as far as making mistakes went for nietzche, he saw a mess up as an instrament to teach. rather than saying, "i've done something wrong" he urges people to take the russian fatalistic approach and say, "something has gone unexpectedly wrong here." remorse about a mistake would be adding a second stupidity to the first.
i think he's using the dionysus view of the world to show that what we now call bad has had different meanings over the centuries. "words are pockets into which now this meaning, now that, now both go into."
he called himself the first immoralist. i noticed you said "will to experience." i wonder what exactly "will" means. it seems to have a lot of different ways it can be used.
i think you got his psychology down pat. he anticipated freud and jong, but i think he exceeded them in seeing through the illusion of the ego. but yeah, its alientation of natural instincts that leads toward anarchy--i like that.
