I learned about The Number: A Completely Different Way to Think About the Rest of Your Life by Lee Eisenberg at The Simple Dollar. Trent, the author of The Simple Dollar, is reviewing a personal finance book every week.

The Number refers to the amount of money that you need to have stashed away at retirement to live the way that you want to. But this book isn’t about how to calculate the Number, it’s about thinking about what you want from the rest of your life. What will you do? What are you living for? Until you answer those questions, you can’t figure out how much it might cost.

The Number is a great book for everyone–people who obsess over their Number, and people in denial regarding savings for retirement.
