One of the things psychologists used to say was that if you are depressed, anxious or angry, you couldn't be happy. Those were at opposite ends of a continuum. I believe that you can be suffering or have a mental illness and be happy - just not in the same moment that you're sad.

Curing the negatives does not produce the positives.

In your own life, you should take particular care with endings, for their color will forever tinge your memory of the entire relationship and your willingness to reenter it.

People who believe they cause good things tend to like themselves better than people who believe good things come from other people or circumstances.

I'm trying to broaden the scope of positive psychology well beyond the smiley face. Happiness is just one-fifth of what human beings choose to do.

The aim of Positive Psychology is to catalyze a change in psychology from a preoccupation only with repairing the worst things in life to also building the best qualities in life.

When well-being comes from engaging our strengths and virtues, our lives are imbued with authenticity.
