You know that saying 'A little knowledge is a dangerous thing'? That's so true of positive psychology. Our latest research tells us that the pursuit of happiness is a delicate art. Certain approaches to seeking happiness are now known to backfire, whereas others are effective.

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.

Love is that micro-moment of warmth and connection that you share with another living being

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

Positivity psychology is part and parcel of psychology. Being human includes both ups and downs, opportunities and challenges. Positive psychology devotes somewhat more attention to the ups and the opportunities, whereas traditional psychology - at least historically - has paid more attention to the downs.

Positive emotions are not trivial luxuries, but instead might be critical necessities for optimal functioning.
