Is Psychological Wellbeing worth prioritizing?

Two independent meta-analyses link dispositional optimism to lower cardiovascular events and all-cause mortality, and a broader synthesis found psychological well-being predicts all-cause mortality independently of the absence of distress — suggesting wellbeing is not just the inverse of mental illness. Weighing that against the numbers, Psychological Wellbeing is reasonable to include, though not a top priority — the evidence is rated strong (72/100), but its estimated effect on longevity is modest (48/100).
