To live as I incline, or not to live at all: so do I wish; so wisheth also the holiest. But alas! how have I still - inclination? Have I-still a goal? A haven towards which MY sail is set?A good wind? Ah, he only who knoweth WHITHER he saileth, knoweth what wind is good, and a fair wind for him.What still remaineth to me? A heart weary and flippant; and unstable will; fluttering wings; a broken backbone.This seeking for MY home: O Zarathustra, dost thou know that this seeking hath been MY home-sickening; it eateth me up.
Friedrich NietzscheConsider the cattle, grazing as they pass you by. They do not know what is meant by yesterday or today, they leap about, eat, rest, digest, leap about again, and so from morn till night and from day to day, fettered to the moment and its pleasure or displeasure, and thus neither melancholy nor bored. [...] A human being may well ask an animal: 'Why do you not speak to me of your happiness but only stand and gaze at me?' The animal would like to answer, and say, 'The reason is I always forget what I was going to say' - but then he forgot this answer too, and stayed silent.
Friedrich Nietzsche
