It’s counterintuitive that something like a physical object that you can keep for a long time doesn’t keep you as happy as long as a once-and-done experience does. Ironically, the fact that a material thing is ever present works against it, making it easier to adapt to. It fades into the background and becomes part of the new normal. But while the happiness from material purchases diminishes over time, experiences become an ingrained part of our identity.
“Our experiences are a bigger part of ourselves than our material goods,” says Gilovich. “You can really like your material stuff. You can even think that part of your identity is connected to those things, but nonetheless they remain separate from you. In contrast, your experiences really are part of you. We are the sum total of our experiences.”
