Louis-Ferdinand Céline

And between whiles you boast of having managed to be rid of your unhappiness, but everyone knows, don't they, that you've not done any such thing but are just as miserable as you well can be. As you grow uglier and uglier and more repulsive, playing this game as you grow old, you can't even conceal your unhappiness any longer, your failure; and in the end your face has become only an ugly expression which takes twenty, thirty or more years to come up from your stomach onto your face. That is what a man will achieve, that and that alone, -- an ugly expression which he has spent a lifetime making and often even then hasn't managed to finish off properly, because of how difficult and complicated an expression it would have to be to reflect his real soul without missing anything out
