Legendary American showman, writer, and famed organizer of “The Greatest Show on Earth”. He bought and rebuilt the American Museum in New York in 1842. His most renowned books are “Struggles and Triumphs”, and “Art of Money-Getting”.
We all know PT Barnum for this circus. What we don't know is the man behind the circus. This book shares some insight into that. There is a lot more depth than you'd expect. He is more than "a sucker is born every minute" (which he didn't even say, by the way). What you get here is his philosophy of work, money, and life. Good advice you may have heard before but interesting in this concept. Like staying out of dept, for example. Over 100 years old and it still applies today. Finding your path, treating people well, etc.
OP, you link is broken.
