F. Scott Fitzgerald said this quote
“ There was one of his lonelinesses coming, one of those times when he walked the streets or sat, aimless and depressed, biting a pencil at his desk. It was a self-absorption with no comfort, a demand for expression with no outlet, a sense of time rushing by, ceaselessly and wastefully - assuaged only by that conviction that there was nothing to waste, because all efforts and attainments were equally valueless. ”
