Is there a term for this?

My limited vocabulary often causes me to spend an absurd amount of time describing in detail rather than referring to a phenomenon by a word or words. For example, nearly everyone is aware that humans have a certain quality about them that is exhibited in the following ways…

We desire products and feel that they will improve our lives in some way. But when we buy them, we find that we’re in the same place we were prior to the purchase, and we continue the cycle over and over.
It’s the same thing that is sometimes described as “boredom” and that leads people to decide that what they need is to re-do their kitchen or buy a new house or car.
It might also cause them to seek experiences. Sometimes it’s an infidelity or a series of short-lived relationships.

It’s more than boredom (another topic that I’ll probably post a question on). It’s a dissatisfied feeling that people express (dukkha?) as boredom or emptiness that seems to motivate much of our behavior.

Is there a term for this? I was recently discussing this with a friend and realized that what we were exhausting ourselves trying to find a term that would best encapsulate this. This happens to me often because my vocabulary is weak.
