Martin Seligman

"P is positive emotion, E is engagement, R is relationships, M is meaning and A is accomplishment. Those are the five elements of what free people chose to do. Pretty much everything else is in service of one of or more of these goals. That's the human dashboard."

"Positive psychology is not remotely intended to replace therapy or pharmacology. So when depressed, anxious or in panic or post-traumatic stress disorder, I am all for therapies that will work. Positive psychology is another arrow in the quiver of public policy and psychology through which we can raise wellbeing above zero."

"Positive thinking is the notion that if you think good thoughts, things will work out well. Optimism is the feeling of thinking things will be well and be hopeful."

"Psychology is much bigger than just medicine, or fixing unhealthy things. It's about education, work, marriage - it's even about sports. What I want to do is see psychologists working to help people build strengths in all these domains."

"The best therapists can do with sadness, anger, and anxiety is to help patients live in the more comfortable part of their set range."
