Why do things prefer to be in the lowest energy state?

Why does something naturally go to its lowest energy instead of the highest? Is that just how it works?

Things in a higher energy state can spontaneously transition to a lower energy state, even of nothing else is around, by releasing energy. But they cannot spontaneously go to a higher energy state if nothing else is around, as thank to energy conservation, this requires an input of energy.
