This book takes a look inside the minds of several well known world personalities, and explores various mental illnesses that they suffered from. This book wasn't as good as I had hoped it would be, but it was decent in providing a broad overview of each figure. I think it gave me a greater appreciation for these figures, such as Abraham Lincoln, who lived their lives in the public while dealing with these issues. I learned about people I had never read about before, which was interesting. Overall, it was a decent book to read.
