Novelty need

Novelty is a psychological need for exploration, personal development, pursuit of interest, new and varied experiences and excitement.

If humans did not have a need for novelty we would never have advanced in the way that we have. We would be in our caves and we would never have looked over the horizon and wondered, and then gone exploring. We wouldn’t have created machines, gone into space, created iPhones or spread across the world. I mean, that might be better, but it is in our nature. We can get ourselves very regulated and comfortable with all of the above in our lives, but then we will inevitably want to change something, want to do something new, find something, or create something.
