Friedrich Nietzsche said this quote
“ Just as in the second part of a verse bad poets seek a thought to fit their rhyme, so in the second half of their lives people tend to become more anxious about finding actions, positions, relationships that fit those of their earlier lives, so that everything harmonizes quite well on the surface: but their lives are no longer ruled by a strong thought, and instead, in its place, comes the intention of finding a rhyme. ”
