There are some good ideas for anyone who is brand new to the world of low cost index fund investing, but anyone who has already read a few books and/or is already on board with dollar cost averaging won't get anything out of it. It felt full of unnecessary examples, repetitive and drawn out messages, and chart after chart of unneeded data. Again, if completely new, it may be good though there are other better intro books and if you are somewhat already acquainted with index investing there's nothing new to learn from this.
