Scientists have shown that because positive and open mindsets produce exploration and experiential learning, they also come to produce more-accurate mental maps of the world.

My all-time favorite topic in positive psychology is the study of positive emotions. I'm fascinated by how pleasant experiences, which can be so subtle and fleeting, can add up over time to change who we become. I'm especially excited these days about investigating how positive emotions change the very ways that our cells form and function to keep us healthy.

I began studying human emotions more than twenty years ago. At that time, almost every scientist working in this area was studying one of the negative emotions, like fear, anger, anxiety, or depression. I wondered why no scientists cared to explain why we humans sometimes feel upbeat and pleasant. I liked the idea of charting new terrain. It's been a fun intellectual puzzle. There's so much to discover!

Flourishing is not a solo endeavor.

Positive people are able to maintain a broader perspective and see the big picture which helps them identify solutions where as negative people maintain a narrower perspective and tend to focus on problems.

When we inject people with positivity, their outlook expands. They see the big picture. When we inject them with neutrality or negativity, their peripheral vision shrinks. There is no big picture, no dots to connect.

The boundaries between you and not-you — what lies beyond your skin — relax and become more permeable. While infused with love you see fewer distinctions between you and others. Indeed, your ability to see others — really see them, wholeheartedly — springs open.
