When 'The Wealth of Nations' was first published, Adam Smith was fifty-three years old. When 'The General Theory of Employment, Interest, and Money' was published, John Maynard Keynes was fifty-three years old. When 'The Capital' was published, Karl Marx was forty-nine years old. When 'A Monetary History of the United States' was published, Milton Friedman was fifty-one years old.
When the book I am going to write in Newyork is published, I will be fifty years old, which is approximately the same as those economics geniuses' average age when their intellectual level was the highest level.
This means that the book will be "the book in my lifetime". I hope that this book can be mutually benefitial both for myself and NYPL.
