P.T. Barnum's 1880 Rules for Making Money, Distilled

A Cool Tools newsletter revisits The Art of Money Getting, the book P.T. Barnum published at 70 after a career that included building a famous New York museum, going bankrupt on a Connecticut clock company, and co-founding the circus that became Barnum & Bailey. The book compresses 20 plainspoken rules drawn from that hustle into a short read.

Four principles get highlighted: choose work that fits your natural aptitude rather than whatever pays, treat debt as a surrender of personal freedom, commit fully to whatever task is in front of you, and guard your reputation because customers will not buy from someone they suspect of cheating. Barnum frames money as a useful servant but a destructive master, and the newsletter pairs each rule with a concrete exercise — auditing your work, listing debts, picking one half-done task to finish thoroughly.
