I haven't done one of these in a while, so this is what I've read this year:
The Art of Learning by Josh Waitzkin - This is one of the best books I've ever read. Waitzkin is genius, and has led an incredible life so far. He has spent his entire life analyzing how he learns and reacts to stimuli, which is why he has the credentials to write this book. I'm just going to go ahead and admit that most people won't like this book as much as I did, because about 25% of it is spent on an idea that I'm obsessed with: slowing down time. Many people have had these experiences - whether it is during an accident or just seeing something incredible - where time slows down to a crawl. He explains how to cultivate these experiences and use it when you want to. Not to mention the other 75% of the book which breaks down the learning process brilliantly.
I, Claudius by Robert Graves - The first historical fiction book I've ever read, and it was very, very good. The story itself is incredible. If you don't know who Claudius was, he was born lame in 10 BC. He hid behind his shell of a body and used his appearance to stay alive during an extremely tumultuous time in Rome, where he eventually became Emperor. Amazingly researched, and while I don't know exactly how much Graves made up, it was an awesome read into an idea of what it was like to live back then.
The Art Of War by Sun Tzu - Obviously a good book, but it didn't impact me that much for some reason. Possibly because I have already read so many of his strategies expanded on in other books. Most of what is in it just seemed obvious by the time I read it.
The Great Santini by Pat Conroy - Lifted out of Tucker's reading list, a well done book with a main character that you shouldn't like, but you can't help to.
Tribes by Seth Godin - I love the idea behind the book, it's one of those things that seems so innate, but having it spelled and fleshed out brings out the beauty behind it.
