Blink, the Power of Thinking without thinking

[slik]

It's a good read, but I'm not sure how much it can help you in poker. It basically tells you to trust your instinct (moreso than your conscious rational mind), but any experienced poker player knows this. This theme is repeated through numerous examples, some of which are nontrivial; poker (had he chosen to include it) would have simply been another such example in this book.
