Greetings, Carl here.

I absolutely LOVE Jeni’s Salty Caramel Ice Cream.

Sometimes, on the way home from work, I’ll stop at the grocery store, buy a pint, and eat it.

That’s right. The whole thing.

Yes, I know. That’s a LOT of ice cream.

I’ve noticed that a very interesting thing happens when I do this:

Bite 1: Best thing in the world, ever.
Bites 2–10: Really good.
Bites 11–15: Good.
Bites 16–20: Meh.
Bites 21+: Okay, now I’m sick.

I learned this lesson the first time I ate a pint of Jeni’s in a single sitting.

And yet, for some reason, I still occasionally repeat the experiment.

Of course, this phenomenon doesn’t only occur with ice cream. This is a well-documented economic principle called Marginal Utility, and (you guessed it) it applies to money, too.

Just like ice cream, beyond a certain point, having more money will not lead to more security, freedom, and happiness.

Fact.

The academic literature on that is clear.

My question is: Why do we devote so much of our time, energy, and attention to having more?

Wouldn’t we maybe be better off if, instead, we focused on having enough?
