The 80/20 Principle, Expanded and Updated: The Secret to Achieving More with Less by Richard Koch

4.0

This book, if the author is to be believed, was one of the first on the 80/20 principle, and as such it is an important book.

The principle is more widely known today, that 80% of the results we achieve, comes from 20% of the effort. Also known as the Pareto principle, it is a figure that can be found in a lot of relationships that we encounter in life (though sometimes 80/20, 95/5, 70/30, etc.).

Having known about the principle for a while, I wanted to read the book as a source for more in-depth perspectives. Koch definietly covers quite a few areas,like business, personal life, money, career, and happiness among them.

I give the book 4 out 5 stars, though I don't know if it's quite a 4. At times I found the arguments could have been better and stronger, and Koch also repeats the line that 80% comes as result of 20% of the effort to the point of it being rediculous. There probably a couple pages (at least) of this sentence (or some form of it). I'm no stranger to "repetition being the mother of skill", but it's just too much here. We get it! Ease up.

What is great, however, is a focused perspective on the different ways that his principle has an influence on our lives, and how we can become more aware of it, which pretty much was my intention for checking out the book.

There's a new chapter in this version of the book, and one that has been removed, however this new chapther is a list of comments from reviewers (both positive and critical ones), but I didn't feel that Koch really answered too well on the critical ones, making the chapter a little bit pointless.

Still, for anyone not familiar with 80/20 thinking, or wanting to know a little bit more, it is worth a look.
