Alain De Botton said this quote

For the rest of history, for most of us, our bright promise will always fall short of being actualised; it will never earn us bountiful sums of money or beget exemplary objects or organisations....Most of us stand poised at the edge of brilliance, haunted by the knowledge of our proximity, yet still demonstrably on the wrong side of the line, our dealings with reality undermined by a range of minor yet critical psychological flaws (a little too much optimism, an unprocessed rebelliousness, a fatal impatience or sentimentality). We are like an exquisite high-speed aircraft which for lack of a tiny part is left stranded beside the runway, rendered slower than a tractor or a bicycle.
