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.

What determines how much time and deliberate practice a child is willing to devote to achievement? Nothing less than her character.

Curing the negatives does not produce the positives.

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.

Optimism is invaluable for the meaningful life. With a firm belief in a positive future, you can throw yourself into the service of that which is larger than you are.

Reaching beyond where you are is really important.
