As I've got older (well, I'm only 45 but have always been old for my age), I've come to appreciate this more. I think this is the key to contentment. Which is different from happiness or joy. I annoy my partner frequently with my ability to go on and on about a certain brand of soap, or I fake getting annoyed at mundane things just for the comedy aspect. But I think, finding joy or wonder or even mild irritation with very minor things helps you to be content. I could sit in a room with my thoughts and be fairly happy, without the need for wifi, social medias, expensive watches, and generally not caring what other people are doing. We are really just flies on a massive dung pile, so we might as well enjoy it
