"To make progress, we need to be able to imagine alternative realities – better ones – and we need to believe that we can achieve them. Such faith helps motivate us to pursue our goals. Optimists in general work longer hours and tend to earn more. Economists at Duke University found that optimists even save more. And although they are not less likely to divorce, they are more likely to remarry – an act that is, as Samuel Johnson wrote, the triumph of hope over experience.

"Even if that better future is often an illusion, optimism has clear benefits in the present. Hope keeps our minds at ease, lowers stress and improves physical health. Researchers studying heart-disease patients found that optimists were more likely than non-optimistic patients to take vitamins, eat low-fat diets and exercise, thereby reducing their overall coronary risk. A study of cancer patients revealed that pessimistic patients under 60 were more likely to die within eight months than non-pessimistic patients of the same initial health, status and age." - Tali Sharot
