To be a virtuous person is to display, by acts of will, all or at least most of the six ubiquitous virtues: wisdom, courage, humanity, justice, temperance, and transcendence.

The defining characteristic of pessimists is that they tend to believe that bad events will last a long time, will undermine everything they do, and are their own fault. The optimists, who are confronted with the same hard knocks of this world, think about misfortune in the opposite way. They tend to believe that defeat is just a temporary setback or a challenge, that its causes are just confined to this one case.

It's a matter of ABC: When we encounter ADVERSITY, we react by thinking about it. Our thoughts rapidly congeal into BELIEFS. These beliefs may become so habitual we don't even realize we have them unless we stop to focus on them. And they don't just sit there idly; they have CONSEQUENCES.

The good life consists in deriving happiness by using your signature strengths every day in the main realms of living. The meaningful life adds one more component: using these same strengths to forward knowledge, power, or goodness. A life that does this is pregnant with meaning, and if God comes at the end, such a life is sacred.

Curing the negatives does not produce the positives.

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.

The pursuit of happiness is enshrined in the Declaration of Independence as a right of all Americans, as well as on the self-improvement shelves of every American bookstore. Yet the scientific evidence makes it seem unlikely that you can change your level of happiness in any sustainable way. It suggests that we each have a fixed range for happiness just as we do for weight. And just as dieters almost always regain the weight they lose, sad people don't become lastingly happy, and happy people don't become lastingly sad.
