Logarithmic Hedonism

Going after nice things often has diminishing returns. Eating a slice of cake is great; getting a second one is definitely not as satisfying as the first one, and... well, with cakes, the 10th one likely has negative utility... but even considering things that scale a lot better (e.g. money): getting a thousand dollars is extremely good news if you're broke, but it's not even worth a bit of attention if you're a billionaire already.

The general approximation to this is that the curve is logarithmic: if you're getting 1 unit of enjoyment out of a dollar, 2 units when you scale it up to $2, 3 units for $4, 4 units for $8... well, this is definitely not how it works in terms of the exact numbers, but "each extra 10% gets you the same fun increase" is pretty plausible.

Is this bad news? It's easy to put it into such terms: "putting in extra work has diminishing returns". On the other hand... you can turn it around:

eating a tiny morsel of a cake is definitely not as good as getting an entire slice, but it's disproportionaly more fun compared to how tiny of a morsel we're talking about. You still get to taste cake!

(even if all you are looking at, to everyone else, is looking like "darn, we missed free cake, nothing is left".)

Same with drinking a coffee: the remaining sip that you completely forgot about & find it 2 hours later is somehow a lot more satisfying, compared to how much you were missing that particular sip when you drank the rest of it.

The same principle applies to doing things, especially if they don't have cumulative effects. Namely, if you generally like biking, going on a ride once per month is... not a lot, but it'll be surely proportionally more fun than any one occasion if you're doing it daily!

(As for "cumulative effects"... well, if part of the enjoyment is being good at it, just doing it once in a blue moon is not going to get you too far. It's a good thing that eating cake does not need a high skill level to enjoy.)
