What I did not know about this book when I checked it out from the library is that it would only help you find the numerological aspects of the personality, instead of the global aspects. It has a nice introduction that explains a lot for those who don't know much about the subject. And also, the method of calculating the personality number is accurate as well. It was an alright read, and because my personality number is a 24/6, I only needed to read one section. I choose to be fair with this review. It isn't the book's fault that I didn't like it.
This book has very detailed and so far, very accurate descriptions of each of the personality traits of the numbers. It's not a book that you should read like a novel, because obviously, there's no way you could remember all the details of each number, from 1 to 31.
It's definitely a book I would like to have for reference though, and with regular reference, you could easily learn to remember the important details of each number.
I love numerology and this is an easy, quick read that shows you how to calculate your personal year and your personality number aka as destiny number.
