See all →Social isolation harms health because lacking supportive people keeps the body in prolonged fight‑or‑flight mode, raising inflammation and stress hormones that wear down systems and reduce happiness.
Believing you fully control outcomes raises your chances of success because perceiving control increases effort and persistence, whereas seeing results as mostly chance reduces motivation and thus actual performance.
Basic ingroup–outgroup loyalties create social distance from outsiders, which reduces empathy and makes harmful treatment of outgroups psychologically permissible.
World-record performances often need favorable external conditions because transient boosts like tailwinds add performance margin that, combined with top-level ability, enable records that ability alone might not reach.

Noticing fortunate events increases happiness because consciously recognizing external good things triggers gratitude, which produces positive emotional responses that boost subjective well-being.
Framing scarcity as either limited quantity or limited time drives action because perceived limits create urgency, prompting people to act to avoid missing out before supply or the window closes.
A practical strategy is to act as if you control your destiny to sustain effort, but also acknowledge luck and use any fortune to help others because belief in control drives persistence while admitting chance prevents overconfidence and promotes redistribution.
