From The Paris Review’s interview with Louis-Ferdinand Céline–
If you could have it all over again, would you pick your joys outside literature?
Oh, absolutely! I don’t ask for joy. I don’t feel joy. To enjoy life is a question of temperament, of diet. You have to eat well, drink well, then the days pass quickly, don’t they? Eat and drink well, go for a drive in the car, read a few papers, the day’s soon gone. Your paper, some guests, morning coffee, my God, it’s lunchtime when you’ve had your stroll, eh? See a few friends in the afternoon and the day’s gone. In the evening, bed as usual and shut-eye. And there you are. And the more so with age, things go faster, don’t they? A day’s endless when you’re young, whereas when you grow old it’s very soon over. When you’re retired, a day’s a flash; when you’re a kid it’s very slow.
