"Reveals a world I never realized existed"
In the 1600s curiosity was looked upon as a sin, trying to unveil the mind of God. Progress was viewed likewise, trying to improve upon the world God had provided. As miserable as their lives were and as horrible as the fate that followed death, people of those days believe "this is the best of all possible worlds." This mindset prevailed for 1,000 years. Fortunately for us, around 1660 there arose a small band of "natural philosophers" who enjoyed experimenting and thinking about the natural world. Isaac Newton, was the genius among them, although his ideas almost didn't get written down, he was so neurotic and anti-social and self-angrandizing. This book's beautifully written and read, very easy to follow. There are a few other books that have changed or enlarged my worldview this much. "How the mind works," by Stephen Pinker, "A short history of nearly everything," by Bill Bryson, and "Longitude," by Dava Sobel come to mind. This book is right up there with them.
"Zig Ziglar is awfully full of himself"
This book is really a series of lectures. It's common sense on steroids. At one point Zig Ziglar recommends that you listen to his lecture series 16 (!) times so that you really incorporate his "pearls of wisdom" into your psyche. He's full of praise for himself, and I found him obnoxious.
