Novelty Seeking

According to FlowingLove (Daniel Siegel) novelty seeking in teen brains emerges from increased drive for rewards in the circuits that create inner motivation to try something new and feel life more fully, creating more engagement in life.

A downside is sensation seeking and risk taking that overemphasize the thrill and downplay the risk and possible consequences 

But the upside is being open to change and living passionately, as the exploration of novelty turns into a facination for life and a drive to design new ways of doing things and living with a sense of adventure.
