The 80/20 principle - the fact that 80 per cent of results flow from 20 per cent of causes - is the one true principle of highly effective people and organisations. This work shows how you can achieve much more with much less effort, time and resources, simply by concentrating on that all-important 20 per cent.

Why You Should Read It: The principles in this book can literally add hours to your days and compound your happiness. It’s worth a look. What’s more important than having time?

Average Read Time: 4.5 Minutes

We’ve all surely heard of the 80/20 Principle, or Pareto’s Law as it’s more formally known. It goes something like this:

80% of the results come from 20% of the effort.
It’s often thrown around in business as nothing more than a buzzword. Few actually do a full 80/20 analysis of their business a...more
I give it five out of five but here's the deal. I think the book itself follows the 80/20 rule. 20% of the book gives you 80% of the value. Do this: Read a short definition of the 80/20 rule on the web. Skip to chapter 9 and begin reading the book. Stop when you finish chapter 11. Read 13 and then skim the rest of the book.

So if you do that the book is 5 out of 5 stars and if you read the whole thing I'd give it like 2.5 stars.

This book is a truly enlightening and motivating look at productivity, time management, and happiness. It shows how to apply the 80/20 Principle to your personal and professional life in order to work less, earn more, enjoy more, and achieve more. The main idea: in business and personal life, “pursue those few things where you are amazingly better than others and that you enjoy most,” and eliminate or outsource everything else. This has immediately become one of my favorite self-improvement book...more
For those proclaiming this book to be life-saver, you will be in for a shock to know that what this book expounds is one of the gazillion other data analysis methods.

Let me explain, there is data and there is information. What you do to the data and in appropriate context makes it information. What the author has expounded in this book is that ‘a little of something causes so much of everything” or rather has stamped an approval (it was not his original idea, remember, only the name “80/20 prin...more

There's a good side to this book and there's a bad side to this book. Good side first. Ever since reading the book I've put 80/20 thinking to use, that is to say that cause and effect are rarely linked in an equal way. 80% of the world's energy is consumed by 15% of the world's people, 80% of hospital costs come from 20% of the patients, 80% of your sales come from 20% of your products etc. It's not so much the "80" and "20" that are the point with this book, it's the theme that the inputs are n...more

This book takes the "work smarter not harder principle" and runs with it, expands it. The central premise is that there is likely a huge imbalance in the effectiveness of your actions (for example, 20% of what you do may be producing 80% of your results) and you should learn what that 20% is - what it tells you about what you are best suited to do - and double and triple down.

There are a lot of chapters that discuss situations in businesses very different from what I do that weren't as engaging...more

It's difficult evaluating a graphic novel adaptation of an existing book. There are two factors at play: the original book and the adaptation.

In the case of this book, I found the book itself to be insipid and repetitive. The author argues that 80% of the results is accomplished by 20% of the effort. Where he comes up with this exact division is not clear. (Why not 78.9% / 21.1%, for instance?) Regardless, he belabors this assertion for page after page, with no real evidence or insight.

But then...more

When I first saw these books, I was both amused and skeptical. After all, I like a good comic but one based on business? I am delighted tosay that this book was wonderful.

The drawings useful in decripting the few writings that at first appeared difficult to understand, illustrator Chris Moreno added depth and contrast to his drawings. However, I did not find the monochromatic artistic portions to be aesthetically pleasing, especially considering the front of the book's bold colours. I would have...more
This book presents the theory of imbalance. Once you get acquainted with the general idea, it should be easy for you to spot the correlation between cause and effect in anything you do.

Whether you will find the book insightful and its ideas relevant will greatly depend on the way you read. True, the book gets quite repetitive at times so I reckon that you use the very same approach to reading it that the book itself recommends. Get the principle and skip to the chapters that are relevant to you...more
I received this book through Goodreads First Reads, and I was excited to see what the SmarterComics series could do. I am a Social Studies teacher and love the idea of a simple and visual way to explain concepts to students. Many students learn visually, and I hoped that the images in a comic-style book would help students who struggle to mentally visualize complex concepts. This isn't the comic from the series I would have chosen, but it's the one I won, and I have to admit I'm a little impress...more
It's OK, but rather repetitive and long-winded at times. The basic point is good and useful: different activities give different value, so it can be useful to focus on the stuff that is most useful and stop doing the other crap. It applies to economics, software development, and all kinds of other areas of life.

As the author mentions, the 80/20 principle is well-known in certain disciplines, including software development (which I have experience in), so the basic concepts were not so radical or...more
I like the concept. Many non-fiction books with one principle idea are too long for the material and end up repeating the ideas or dragging out the explanations. I think this is a good presentation that makes the sound-bites easier to remember.

The places where he broke the fourth wall looked a little too much like an infomercial to me. I would prefer keeping the author out of the illustrations, but I would be interested in reading more non-fiction books in this format. It's a much quicker way t...more

"The 80/20 Principle" is a must-read about how to get the most out of your life. The book's thesis is that in complex, non-linear, real-world systems, 20% of the inputs often generate 80% of the result. This means that if you focus on the right stuff and ruthlessly eliminate stuff from the other 80% of inputs, you can double your results with half the work. Very useful parts of this book included "80/20 charts", emphasis on simplicity, locking in great customers forever with superior service and...more
I wanted a lot more from this book, which was recommended to me by my sleep dr. It had some good reminders in it, but I feel like I'm already doing a lot of the principles. However, it was a good reminder to slow down and that you can achieve a lot without being busy and overexerting oneself. Also a good reminder to cut a lot of unnecessary crap.

Hmmm, maybe it was more useful to me than I thought.
Layered, succinct, and thought-provoking. I only wish the graphic novel was in color. I feel like the SmarterComics adaptation captured the 20% of information that provides 80% of the impact. Overall, fairly enjoyable.
In the words of Peter Drucker, "Efficiency is doing things right, effectiveness is doing the right things." This book is about discovering and executing the right things.
boring. Talking book, couldnt get into it. Seemed to be making a big fuss about the obvious

A quick, to the point read about a principle with a lot of potential. I didn't feel like the author belabored the point like a lot of other reviews I read ahead of time complained about. I found the part about business extremely interesting and actually began discussing the principle and possible applications for my team with my boss even before I finished the book. I found the discussion about applying the principle to one's personal life a little less cut and dry and even nebulous at time. Sti...more

Recommends it for: People interested in effectivess and efficiency
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...more
I didn't finish this book...I could say the reason why is that I learned the principle he was teaching (20% of the effort accomplishes 80% of the results) in the first 20% of the book and didn't need to read the rest, but it was actually because it was due back to the library...

I don't remember much of the actual book, but the principle really stuck in my mind. And the more I've observed my own behavior and of businesses, etc. the more I see that a large chunk of the work really is finished with...more
The 80/20 Principle: The Secret to Achieving More with Less

Revelation? Towards the end of the book- yes, unexpectedly the book started to get more and more interesting, imparting with wisdom from various psychologists, from Maslow, Goldman to Seligman.

The book gives priceless advice on ...happiness. one suggestion which appeals to me is – Exercise!
After a long period of laziness, I started exercising and I can confirm what Koch says and experiments prove: exercise makes wonders f...more

The book takes Pareto’s Principle and applies it to business and life. The Italian economist Pareto (long deceased) found that a minority of causes, inputs or effort usually leads to a majority of outputs, results or rewards. In other words, 20 percent of the effort gets you 80 percent of the results. It’s not always 80/20. Sometimes it’s 95/5 or 70/30, but 80/20 is the shorthand for saying that the majority of effort put into an endeavor is, largely, meaningless. Anyone who has worked for a gov...more
The basic principle described in the book, Pareto's Law, is very useful almost regardless of what you do. The book explains the law well in several scenarios. It was also nice to see explained in detail the fact that the "80" and "20" add up to "100" is just a coincidence.

However, the author makes many generalizations that aren't practical. Putting most of one's eggs in one basket isn't a great idea for the masses when it comes to stock market investments. Outsourcing all but the most "productiv...more

The ideas presented in this book are all very refreshing and challenging.
In this book, Richard Koch will introduce you to the imbalance of the way of the world and how you can make use of this imbalance in your life.

There are two aspects to the 80/20 principle from the author's viewpoint:
1. 80/20 Analysis and
2. 80/20 Thinking
I believe you need to first inculcate 80/20 thinking - which is widely and heavily written in this book - before you can effectively be 80/20 analyzing. In a nutshell, thi...more
Ironically, the first part of this book did not impress me. However, I came upon the key 20% later on and can speak much more highly of the work now. The writing itself is typical for this genre of business book with the work "principle" in it. Still, the author takes a basic concept and expounds on it in such a way that should make any reader wonder why they haven't applied such common sense before. Koch states that this concept has never been covered in a book specifically dedicated to that pu...more
I've always disliked books about business in general, partly because most of those books only talks about things that everyone knows like:

-Hard work
-Set goals
-Use time wisely
-Set priorities
-etc.,etc., and etc.

Please, these are all just mumbo-jumbos, and anyone that think this kind of book is great certainly never experienced the real world of business and marketplace.

Oh, I haven't. I'm still in college trying to get my bachelor degree, but even right now, easy, one sided answer neve...more
I get it. 80% results from 20% effort. I got it before reading this book. Nothing new was shared, there's not really much more to it than that.
I read 100 pages of un-credited examples, made up company names and far reaching generalizations. The point was made through the title alone. The table of contents added some details and ideas on where this phenomena can be found, but really, there was nothing profound here outside of 80/20 itself.
I skimmed the last half of the book hoping something woul...more

80/20 is an interesting phenomenon. It is not a universal principle like gravity, but still worth investigating, especially as it relates to time. If 20% of my time yields 80% of my effectiveness, then it behooves me to focus on leveraging the 20%. I got lost in the middle of this book - very technical and the author's uses mgmt consulting jargon. There is a pervasive philosophy in this book that control - of happiness, success, fulfillment, relationships, etc - rests entirely in our hands. True...more
