Speed reading is like driving a car. You want to go faster, but because of what you've learned before, you are limited by your driving habits. By breaking those habits, and practising the new way to drive, you will be able to open up a whole new world of speed, and get to your destination much faster.
If you think the paragraph above is useful, and helps you understand the concept of reading faster, get this book.
If, on the other hand, you think the paragraph is stupid, as you can understand basic concepts without it being explained by a car analogy, then do not buy this book.
It has a few good tips interspersed with 90% filler - and even then, it's a very short book. As I said above, I could barely read it, due to each chapter starting with about 2 pages worth of the aforementioned car metaphor.
It's also filled with other nonsense - for example, goes on a complete meander about your personal time management - I nearly dropped the book in the bin when it recommended that I use "Google or Yahoo as they give better search results, and you'll save time by using them". Yes, that golden nugget of information is actually in here!
Saved from a 1 star rating as some of the tips are definitely quite good.
