The wisdom of US Presidents has instructive and inspiring quotations from every President from George Washington through Barack Obama. Most of us know something of the most generally respected six: George Washington, Thomas Jefferson, Abraham Lincoln, Teddy Roosevelt, FDR, and Ronald Reagan. But don't over look the others such as John Adams, James Madison, and James Monroe who helped draft the Bill of Rights and Constitution; Monroe also was critical in obtaining the Louisiana Purchase, the largest real estate deal in history, as John Adams was in being our first non-unanimous President and launching the famous Adams Jefferson letters, perhaps the most profound series of insights into the American Presidency and founding of the country. You may well be surprised by the insights of so many others such as Andy Jackson, James Polk, Franklin Pierce, James Garfield, Calvin Coolidge, Harry Truman, and all of the others.
