We would explain this ourselves, but the quote below from Barack Obama's national proclamation is better than what we can come up with.
"Entrepreneurs embody the promise that lies at the heart of America -- that if you have a good idea and work hard enough, the American dream is within your reach. During National Entrepreneurship Day, we renew our commitment to supporting the entrepreneurs who power the engine of our Nation's economy. These intrepid individuals translate their vision into products and services that keep America strong and competitive on a global scale, and build opportunity and prosperity across our country.
NOW, THEREFORE, I, BARACK OBAMA, President of the United States of America, by virtue of the authority vested in me by the Constitution and the laws of the United States, do hereby proclaim November 14 through November 20, 2010, as National Entrepreneurship Week. I call upon all Americans to commemorate this week with appropriate programs and activities, and to celebrate November 19, 2010, as National Entrepreneurs' Day."
