I'm interested in self help books in general, especially any business related or around the topic of personal finance. This book particularly stood out for a number of reasons.
Firstly the book contains detailed and easy to follow information to enable you to understand the nature of budgeting, setting realistic goals and tracking them over a period.
Secondly, it includes worksheets which are available on a CD or downloadable which come in excel or PDF format. I'm a paper person so I like sitting down and number crunching. The thing is that these work very well and I can see by budget taking effect.
Finally, the budgeting software that comes with it. Its excel based, however as you enter the data the software springs to life showing you graphs and charts which easily explain your financial position. It tracks your goals, your spending etc and when your doing good or bad, It tells you.
This is hands down the best budgeting book I have came across.
