Why the second slice never tastes as good
Think about the last time you were really hungry and the first slice of pizza arrived. That slice was perfect. The second was good. By the fourth you were eating because it was there.
Economists call this diminishing marginal utility, which is a terrible name for one of the most useful ideas you will ever learn. Each extra unit of something gives you a bit less than the one before.
Once you see it, it is everywhere. The first coffee of the day is a small miracle. The third is a habit. The first week of holiday is bliss. Week three you are checking email. A pay rise feels enormous for two months and then becomes the new normal.
Here is the practical part. Because the first unit of anything gives you the most, you get more total pleasure by spreading things out than by piling them up. One great meal a week beats three average ones. A short holiday twice a year usually beats one long one. Small, frequent, and separated wins.
It also explains why the richest people you know do not seem proportionally happier. The hundredth thousand does far less than the first.
The next time you are about to reach for the fourth slice, ask what the fourth slice is really giving you. Often the honest answer is: not the pizza.
