No one writes anything worth writing, unless he writes entirely for the sake of his subject. - Arthur Schopenhauer

Sleep is the interest we have to pay on the capital which is called in at death; and the higher the rate of interest and the more regularly it is paid, the further the date of redemption is postponed.

All happiness is of a negative rather than positive nature, and for this reason cannot give lasting satisfaction and gratification, but rather only ever a release from a pain or lack, which must be followed either by a new pain or by languor, empty yearning and boredom.
