" A very helpful collection of concrete, practical, yet isolated, tips. At first, I found it a bit strange as these tips come from different angles, but at a later stage I valued the way the collection is presented. All the tips drive you to adopt a global view about how to approach things and how to build your attitude in so as to think BIG. I will re-read it again and again. Very enjoyable. "
