Richest Man in Babylon is a classic for a reason.  Highly recommend the principles such as budgeting, spending with the end in mind, acting in a way so as to respect yourself, and investment that generates income,etc., are all good.  But, as a friend reminded me, applies best to sound money.  It is an underlying assumption of his argument.  Gold worked then, still kind of does, but the RMIB applies better using Bitcoin than inflationary fiat as you are unable to outsave debasement.  So read it yes but understand the new playing field.
