To be honest i didnt expected to much. But for this price i gave it a try.
And it was totally worth it. The strategies in this book are easy to follow and the six ones that I already implemented in my day, work great. They seem like common sense and maybe they are, but without the book i would have never thought about them.
Plus the book is not to long, but well explained and easy to read.
I would definitely recommend to buy it.
