There is some usful information on here but it is overly wordy and fluffy. The first 96 pages can be basically summed up as 'favour tracker funds, keep costs down, and don't try to time the market.'
A lot of the book is repetitive and states the obvious, but multiple times in sightly different ways.
Also strange is that the appendices have arguably some more useful (practical) content than the rest of the book, with short steps and tables to help you actually implement a strategy.
If I was going to read this again, I'd skip straight to at least part 3, possibly even chapter 7 starting on page 117. As long as you are on the same page that index funds are the backbone of a 'smarter' strategy, there's really not much in the opening chapters other than trying to convince you what you probably already know. A few interesting quotes and things are dotted around the place though.
The author mentions how his friends jokingly said he should make sure it's only a pamphlet size when he said he was going to write it... To be honest I don't see why it couldn't have been, into something about 1/5 of the size and still having the same value.
