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 goes beyond happiness, or satisfaction with life. True, people who flourish are happy. But that's not the half of it. Beyond feeling good, they're also doing good-adding value to the world.

It turns out that unexplained positivity lasts longer than positivity we analyze until we fully understand it.

Positivity doesn't just change the contents of your mind...It widens the span of possibilities that you see.

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.
