I finished this book today. For many on the MMM site it is a review, but I did get a couple of things out of it.
I liked his explanation of risk, diversification, and "self cleansing" of VTSAX.
I learned a little from withdrawal strategies to minimize taxes.
I also liked that he gave an example of a 4% withdrawal from many sources. It may not be the way I do it, but hey, i got some time to think about it.
Also some excellent thoughts and considerations on dealing with SS.
The book was written like I was sitting next to him at the bar having a beer and picking his brain.
