But it is quite fooling yourself to call everything you have to do fun. Come on, cleaning cat's corner is not the same fun as playing with mum. You clean cat's corner to have actual fun later (better smell in the room, happier and healthier cat), or rather, to keep having (perhaps diminishing) fun with the cat.
In a sense, we can bring now all desired experience to the common fun denominator because we can afford to. (So far, perhaps.) In harder times, you do things for living, not so much for fun.
Habits and prejudices can be stronger than drive for pleasure, for (mostly) good reasons.
