I learned that hard work is an essential part of life - that by and large, you don't get something for nothing - and that America was a place that offered unlimited opportunity to those who did work hard. I learned to admire risk takers and entrepreneurs, be they farmers or small merchants, who went to work and took risks to build something for themselves and their children, pushing at the boundaries of their lives to make them better. I have always wondered at this American marvel, the great energy of the human soul that drives people to better themselves and improve the fortunes of their families and communities. Indeed, I know of no greater force on earth.
