I think it’s a book. The biggest lesson I took away from this book was to make someone feel like an important person. If I had to pick one sentence that represents this book, I think I’d choose that one. Using a method I read about in this book, I experienced for the first time how one person’s attitude could change by 180 degrees. That’s why I sincerely recommend this book all the more. And with that, my book recommendation content has come to an end.
