I think the book is basically about how to make your life easy and not only easy but doing it the right way and how you going to enjoy the things that you are doing. So of course to enjoy the things that you are doing you should have passion on it and not thinking all the time how would you defeat your competitor, it is said there that if you fulfill your customers wants then that is enough and continue on the thing that you are doing.
It is also discuss in the book that you should maximize your product, I mean you should sell enough product for the day so you would not waste time, effort, and your funds in doing the product. It is also discussed there that if your competitor sell faster or do their job faster then your not going to compete in their game that they are playing but instead play in ” Your Game ” so sell cheaper, in other words you should let your competitor play with your game you know and not play with his game that you know he would handle it very well.
Another thing that caught my attention in the book is that you should also think critically. I mean you should disregard the things that are not necessary or the things that are useless. For example if there is a thing that you would like to bring everyday but that thing does not have to do anything or does not have any use at all in your daily life then its better to leave it at home because it might destruct you for that day and might cause failure for that day.
