“The older man should know that his life is not rising or expanding, but an inexorable inner process produces a contraction of life.
For youth is almost a sin or at least a danger to mind too much with himself, but for the man who grows old is a duty and a need to devote serious attention to your own self.
After having wasted light and light about the world, the sun gathers its rays to light yourself. Instead of doing the same, many elderly individuals prefer to be hypochondriacs, covetous, dogmatists and laudatores temporis acti (praisers the past) and even teenagers, pitiful substitutes enlightenment of the self, an inevitable consequence of the illusion that the second half of life should be governed by the principles of the first. ” ~Carl Gustav Jung – The Nature of the Psyche
