Sage, time-honored investing advice from one of the industry's best. This is essentially a distillation of the wisdom and guidance already found in Charlie Ellis's previous publications, the best of which is Winning the Loser's Game: Timeless Strategies for Successful Investing. In all honesty, this precis is a paradox: those who can readily understand the economic language used already know the content.

5 stars for the man and his messsage; 3 for the book itself.

A rehash of his previous books

Not worth the time if you’ve read his previous books. His book Winning the losers game” is the one to read.

Three word review: Power of Compounding!

Longer review: If you are early in the adulting journey, this short book provides a clear and simple road map for building wealth over the long term. It would be an excellent gift for a college grad or to celebrate a first "real" job (along with some $$ for that first 401k).

But this is also an excellent primer for any one who needs to be reminded that it is not only nearly impossible, but also not at all necessary, to try and time or "play" the markets, to achieve financial success.

Spoiler alert for both audiences... the keys are:
- low cost investing
- consistency of saving
- match the match (if available)
- and time (be patient; see also the three word review).

Folks approaching retirement might also benefit from Chapter 9 (only 4 pages!) which provided me with a valuable and different way of thinking about the Tobin rule of 4% withdrawals.

A bonus was learning a bit of the history of investing and why it is no longer possible to beat the experts.

This book isn't for everyone, but for many, following its simple principles could be life changing over the long haul.

For the bulk of this slim book Ellis argues at length on why it is best to invest in index funds. His reasons seem sound. But I still don't really understand what they are. I'm sure this book is too basic for most people interested in the topic, but for the novice it was not too helpful.

As for his other ideas:
1. Invest early (sorry, but I can't time-travel)

2. Scrimp and save everything so you can invest (I'm pretty damn frugal already, but also the author doesn't seem to realize that there are things in life more important than money and investing)

3. Get a job with a good 401K (the author is 88 years old and totally out of touch with today's job market)

4. Disputing myths about bonds (no problem here, I'm sure he knows what he's talking about)

5. Don't collect social security until you're 72.5 (okay, I'll try, not sure if will be able to wait that long, also not too confident that social security will even exist by the time I'm eligible)

Great guide missing important pieces

The advice is classic Ellis. It’s flaw is failure to consider the potential issues created by the failure of the dollar which is unfortunately increasingly likely over the next 20 years. In addition, more analysis of the high probability the social security benefit will be reduced in 2023 by 22% to 25% if congress fails to act. Which unfortunately they have shown no inclination to do.

Information to word ratio pretty high. (Short book.)

Most interesting to me was author's opinion that one's home equity and future social security earnings should be counted in one's net worth investment ratio of stocks/bonds as if they were bonds. He advocates for ignoring advice such as "invest the percentage of your age in bonds in your total portfolio."

Total has typo, and the book has misinformation about Social Security

The title has a typo in it, and the book has misinformation about Social Security. The book says that you can maximize Social Security at age 70 1/2; actually, the maximum age is 70.

A concise yet profoundly insightful guide on how ordinary individuals can achieve investment success. Reading this short book and applying the lessons to your life early on could make people a lot of money in the long run. I only wish I had this book sooner.

Good basic book- invest in index funds over the long term. Some other interesting notes about the value of delaying social security, staying away from bonds, -and the fee structure of actively managed accounts and how they can bite into value over the long term

As someone who is just learning about how to invest and trying to dig through the myriad of ways to do it, learning about investing feels overwhelming. This book had really helpful advice and reasoning to hold onto and was a quick read of helpful concepts. I will be checking out his other books!

It's an overview book, but is full of information. A good book for an early investor and a reminder for a seasoned investor as well.
