For people who have studied economics, you might recall the law of diminishing marginal utility. The law applies very well to money but we seldom think of money that way.

What is Diminishing Marginal Utility?

The law of diminishing marginal utility says that the marginal utility from each additional unit declines as consumption increases.

So the classic example, goes something like this. When a hungry consumer eats one piece of pizza. They gain a ton of utility. However, as they get full, the satisfaction from each additional slice gets lower and lower. The first slice of pizza is fantastic. You hadn't eaten all day and that sumptuous slice of pepperoni and cheese never looked better. Or as Sheldon would say, "My favorite shape of food – a circle made of triangles served in a square box." The second and third slices are still good, but not nearly as satisfying as the first. By the time you finish the whole pizza, you're stuffed. There's no additional utility from an additional piece.

Money works the same way. We are constantly focused on what we could do with a little bit more money. We have this one on one perception of income and satisfaction. If I make X amount of money, I will receive Y amount of satisfaction.

But, as I laid out, after a point additional money has no additional utility.

Perhaps, that's why time becomes ever so important when you have a lot of money.
