The message of the book is very easy to understand. It boils down to not having fear or letting fear and emotions control our reactions. Always STOP, CHALLENGE and CHOOSE in the face of crisis. Stop to think. Challenge your moment's thoughts and reactions. Choose the optimal course of action. The definition of the author for winning is lovely indeed: to do the best that one can with all that one has.
Now, in terms of implementation, there is a lot of space devoted to the what, but barely one chapter devoted to the how to put the book's ideas in practice, although it's fair to say that there's a good number of examples and cases brought forward. The second to last chapter is dedicated to putting together a Statement of Purpose, followed by a Vision and a plan to set it all in motion, but I can't help remembering the level of detail that Stephen Covey goes into in his book "The 7 Habits..." when discussing this same topic, and this is one that he covers early on in his book, devoting the rest of it to ways to make it happen.
All in all, it feels like a useful Step 1 book, whose key message (STOP, CHALLENGE and CHOOSE) is helpful to have present at all times, but not a book that will help make a huge step in changing your life for the long term: it falls short in some aspects, which is why I recommend Stephen Covey's work more.
