Rather than considering human potential in terms of an unrealized desired state, what if we framed it as gaining momentum in worthy long-term pursuits? This conceptual article, integrating ideas and findings from several scholarly literatures, explores how life purpose can serve as a meaningful, intentional guide for individuals, especially youth, to direct their other potentials into prosocial contributions to society. The argument (a) considers life purpose itself as a form of intrapersonal giftedness different from academic giftedness; (b) describes how life purpose could include distinctions of further potentials: coherence among purpose dimensions, influence on different life domains, reach of others impacted by the youths’ contributions, emphasis to change society, and precocious emergence of purpose’s dimensions and distinctions; and (c) muses how life purpose’s directing of other potentials might become a potential that could be realized by all youth.
