This particular book by Hawking explores his personal life as well as the physicist side of life. I become interested in how a man like Hawking came to be after reading his "A Brief History of Time." This book answered all of my questions as he goes farther into depth about how he grew up, and lives with ALS. This book is a composite of many essays, so the reader will find that Hawking repeats himself more than twice. This is a good book, but not quite to the standard as his previous book was. I gave a rating of 4 stars because the title of this book was somewhat deceiving, as an aspiring physicist looking for an educational book might choose this one, little realizing that it focuses much on Hawking's life, instead.
