Sounds to me like what people are identifying as dopamine, generating it and enjoying it. I am not educated though about brain function.
Noticing novelty is beneficial in nature as it surfaces opportunities to conscious level. "Squirrel!" famously, from the movie "Up". It feels good to experience. Then, creating ones own dopamine supply can drive behavior, and increasing the number of behavior can exhaust energy supply on different human dimensions.
So now, managing this process and limiting the dopamine cycle becomes also worthwhile -- avoiding fatigue potentially perhaps -- while still not negating the attractiveness of dopamine derivable from the endless opportunities of the world. <3
