The postscript of the book is kind of the history of the US consumer. I think it might actually be my favorite, just connecting the dots. The chapter on reasonable versus rational might be one of the most meaningful to me in terms of changing my own life. And even if there are things that you do with your money that don't make sense on a spreadsheet, they don't made sense on paper. If they work for you, if they're reasonable, then it's the right thing to do.
