Douglas Adams famously answered 42 – highlighting the absurdity of expecting a simple answer to an impossibly complex question. The real insight isn't the number but that we're probably asking the wrong question.
Philosophers offer frameworks: Aristotelian flourishing through virtue, existentialist meaning-creation despite absurdity, utilitarian well-being maximization.
