If we want to grow, we need to add energy.

There's an energy in New Things.

It is clear - if we want to grow, we need to do New Things.

***

People need and seek novelty, challenge, & [curious as it may seem] struggle. 

When people do not perceive novelty, challenge, or struggle they pine and become lacklustre.

Innately, people know it is essential to add to energize.

Small, wisely chosen New Things deliver enormous energizing value. New Things cure boredom; New Things expand and focus pupils; New Things stretch the mind and the body.

Simply put - New Things enliven.
