If there is one thing that characterises an “All-American” it is their infallible cheery outlook on life. Unlike the British, renowned for their cynicism, the Americans seem to maintain eternal optimism even when in the direst of straits.
Andrew Carnegie once commissioned a young writer to interview successful Americans to find out the key to their achievements. He discovered that the key to success did not in fact lie with innate intellect or wealth, but simply the conviction that they would achieve. This positive attitude embodies the American culture and inevitably led to the US becoming the most powerful country in the world.
