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.

Positivity transforms us for the better.

Positivity opens us. The first core truth about positive emotions is that they open our hearts and our minds, making us more receptive and more creative.

Love is a momentary upwelling of three tightly interwoven events: First, a sharing of one or more positive emotions between you and another; second, a synchrony between your and the other person’s biochemistry and behaviors; and third, a reflected motive to invest in each other’s well-being that brings mutual care

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.

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.
