Perhaps the most important traits to foster and develop throughout the life span are those in Factor III, Conscientiousness. Conscientious people are more likely to have a doctor and to go see one when they’re sick. They’re more likely to get regular medical checkups and to reliably keep up with their professional, family, and financial commitments. This may sound like a mostly practical matter, but Factor III traits are highly correlated with a panoply of positive life outcomes, including longevity, success, and happiness.
