Of course, we do not always have the opportunity to accompany these people up close and absorb firsthand what they can teach us. But that is why books exist. So, returning to the initial question, yes, I do believe it is possible to learn something from books like Donald Trumps. Obviously, I am not saying that by simply reading the book you are guaranteed to become as rich as Donald Trump. What I am saying is that after reflecting, digesting and adapting what he has to say, you may get a new insight into solving an old problem, or you may get uplifted and be able to get back up on your own two feet and continue your march forward. Or you may begin to question your methods and imagine new ways to proceed. And if any of these possibilities truly happens, then the book will have served its purpose.
When Trump speaks about things like thinking big or being passionate about what you do, skeptics rush to accuse him of creating a list of obvious ideas. The fact of the matter is, there is no secret and bombastic ingredient capable of making someone an instant success. From this perspective, the greatest revelation in Trumps book is to show that the ingredients for success are always the same: determination, passion, enthusiasm, effort, and hard work. How to manipulate them and use them in your favor, with utmost efficiency, is what really makes the difference. And that is something only those who do it can teach.
