At a certain point, buying more stuff isn't going to make you happy. However, some things you can buy absolutely will make life better. This Fulfillment Chart helps you figure out which is which.
As personal finance blog The Freedom From Money explains, there is a curve of fulfillment that most of us experience when it comes to the things we spend money on. Above things like basic survival and comfort, a few expenses can make us feel happier. Past a certain point, though, it moves into extravagance and spending more money is just wasteful.
While it's hard to define this for everyone, plotting your own personal purchases and desires along this chart can be helpful. For example, how large a home would you have to buy to have enough? How much would be considered extravagant? Is there an upper bound to how much money you could spend while still making yourself happy? If you're planning your life and can't find where the things you spend money on might land on this chart, it may be a signal to re-prioritise.
