New Books

While sticking with the topic of critical thinking, i have decided to find some new reading material. At first i was centralized in the self help section, skimming through readings on how to try and achieve enlightenment, peace, and lasting Joy. I bought a book called "The Power Of Now A guide to spiritual Enlightenment" by: Eckhart Tolle. I will post a review on it later. Also, while perusing the Non-Fiction section, i found myself interested in biographies. What makes great people as such? I'm not talking about ass-hats like Russel Brand or sports figures like Alex Rodriguez. I believe it is important to know how people like Thomas Jefferson, Napoleon Bonaparte, Franklin Roosevelt, Robert E.Lee. People with the influence to shape a nation. If anyone has any recommendations on some non fiction books to help better yourself, let me know.
