“One should always be in love. That's the reason one should never marry.”

The Mysterious Affair at Styles (1920)

L'amour a toujours été pour moi la plus grande des affaires ou plutôt la seule.
La Vie d'Henri Brulard (1890)
Variant translation: Love has always been the most important business in my life, or rather the only one.

Light (1919), Ch. VII - A Summary
Context: On Sundays, among the crowds, I have often felt my heart tighten with distress as I watch the unknown women. Reverie has often held me all day because of one who has gone by and disappeared, leaving me a clear vision of her curtained room, and of herself, vibrating like a harp. She, perhaps, was the one I should have always loved; she whom I seek gropingly, desperately, from each to the next. Ah, what a delightful thing to see and to think of a distant woman always is, whoever she may be!
There are moments when I suffer, and am to be pitied. Assuredly, if one could read me really, no one would pity me. And yet all men are like me. If they are gifted with acceptable physique they dream of headlong adventures, they attempt them, and our heart never stands still. But no one acknowledges that, no one, ever.
