Success requires persistence, the ability to not give up in the face of failure. I believe that optimistic explanatory style is the key to persistence.

So Positive Psychology takes seriously the bright hope that if you find yourself stuck in the parking lot of life, with few and only ephemeral pleasures, with minimal gratifications, and without meaning, there is a road out. This road takes you through the countryside of pleasure and gratification, up into the high country of strength and virtue, and finally to the peaks of lasting fulfillment: meaning and purpose

You go into flow when your highest strengths are deployed to meet the highest challenges that come your way.

Not only do happy people endure pain better and take more health and safety precautions when threatened, but positive emotions undo negative emotions.

Ten years ago, when I was on an airplane and I introduced myself to my seatmate, and told them [I was a psychologist], they'd move away from me. ... And now when I tell people what I do, they move toward me.

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.

Curing the negatives does not produce the positives.
