I am writing this book for anyone who wants to change their lives for the better. If you go to work and feel that “this is not mine”, if every morning you wake up is meaningless, and life begins to resemble Groundhog Day, passing according to the routine “home-work-home” schedule, this book may be for you. Work is not only a way to earn money, but also a great way to fulfill yourself. Sometimes, even with a good salary, you realize that you are not fully realized.
