Condensed good tips

This book has a very small size (12 cm x 8.5 cm, 159 pages) but a large content !!! It is enjoyable to read, written in a simple style with a simple, clear and direct. It tells us much about human behavior and gives us the codes to be self-perceived well and achieve its ends, the soft method depending on the objective: how to be obeyed by his children? know how to speak to women / men? make good use of the phone? emm ... neutralize the office? etc ...
I highly recommend.
