This is another book I read a few years ago. It's a well written defense of the 50 (must haves): 30 (wants) :20 (savings) budget. (Although as Mustachians I suppose we should be aiming for something more along the lines of 40: 10: 50. I liked their concept of balance --they do a nice job of drawing attention to the importance of not having "must haves" exceed 50% of your total income. They also have a concluding chapter that discusses what to do if you were to be hit by a financial disaster.
