It’s tough to know if you want to purchase that cool thing because the thing, in and of itself, would bring you joy or because it would deliver you status (and perhaps joy through that gained status).

In that scenario, you’ll quickly learn what material goods cleanly deliver happiness (and should be purchased) and which ones were mostly about how others viewed you (and should be avoided).
