"A sage once reduced all virtue to the Golden Mean. Push right to the extreme and it becomes wrong: press all the juice from an orange and it becomes bitter. Even in enjoyment never go to extremes. Thought too subtle is dull. If you milk a cow too much you draw blood, not milk." - Balthasar Gracian's "The Art of Worldly Wisdom"
All good and all bad things approach a point of inflection when driven toward their purest and greatest realization. In the kosmic cycles of enantiodromia all things are kept in balance. Every summit precipitates a descent. Every valley leads up to an ascent. It is the lot of man to suffer the good and bad in turns and in equal measure. Thus seek moderation in all things in order to suffer little Fortune's caprice; that way you can breathe of the air of freedom from Fate and thereby become the sole author of your joys and woes.
