C.s. Lewis said this quote

“ As the uneasiness and... reluctance to face [his problems] cut him off more and more from all real happiness... habit renders the pleasures of vanity and excitement and flippancy at once less pleasant and harder to forgo... All the healthy and outgoing activities [he shouldn't want to avoid] can be inhibited and nothing given in return, so that at last he may... I now see that I spent most of my life in doing neither what I ought nor what I liked. The Christians describe [Heavenly Father] as one without whom Nothing is strong. And Nothing is very strong: strong enough to steal away a man's best years not in [dire] sins but in a dreary flickering of the mind over it knows not what and knows not why, in the gratification of curiosities so feeble that the man is only half aware of them... in the long, dim labyrinth of reveries that have not even lust or ambition to give them a relish, but which, once chance association has started them, the creature is too weak and fuddled to shake off. ”
