People are usually very reluctant to read a great people biography, because they fear that if the author is not at least somewhat knowledgeable, then their reader will know what to expect from the book. However, a people's book by itself doesn't need to be the pinnacle of intellect or academic brilliance, it just needs to contain some good information on the person it's about.
People often forget that they're reading a biography of themselves. Sometimes it's easy to read the book with the mind's eye of a third party and see where the writer was coming from while writing it. While reading a book, remember that you're reading it as if you were the author, and not someone else who's in the same position as you, so you can expect a different kind of perspective.
A great people biography will contain many personal anecdotes and stories about a person's life. If the book contains a lot of interesting facts that were well-documented, then you can be sure that the book will provide great insight into the personality of the person that was written about. This will help you understand the real person behind the person that you've read about, and this insight can help you make better choices about your own character.
Often, the best people books contain some sort of personality traits that are common amongst the writer. For instance, in a recent study conducted by the Personality Assessment Center, they found that people who are introverted or are more reserved are more likely to come up with unusual ways of solving problems or facing new challenges in their lives. The same was true for extroverts, which were also found to possess a unique way of thinking and reacting to situations.
Other types of interesting anecdotes about people include how they dealt with depression or how their parents or grandparents dealt with difficult emotions. A great book about personality, such as a biographical book about someone's life, may also contain a list of family members. This is called a "family tree," and is often a great way to learn more about a certain person.
