content: This is a great book for anyone 20+, who is working and thinking they have it made. As a recent early retiree baby boomer, everything in this book rang true. It's not about the "number", it's about how you spend it and how you need to be prudent in your working years.In addition, the book reads like a novel. I couldn't put it down. Eisenberg's writing is phenomenal. B. Slomka
