For problem solving lovers - following are the list of books that i have read and most of them has amazingly influenced my thinking. Books are listed in no particular order, bolder ones are classics. I hope to write small review of each one of them... Please do comment with your list

Conceptual Blockbusting by James Adams
Everyone of us lot mental blocks to tackle a particular problem/situation in life. Some of the blocks are the result of how our brains are hardwired, but there are lots of other blocks which can be potentially overcome by becoming aware of them and consciously working to avoid those blocks. What I liked most of this book is that Adams is actually able to categorize them into different categories and exercises are simply the best. I have read it many times and will keep reading it many times... knocking down blocks one by one

The Universal Traveler by Don Koberg and Jim Bagnall
Provides a structured framework which can be applied to any problem at hand. By taking the metaphor of "Travel" which everyone is quiet acquainted with, authors has structurally provided step by step guide to handle problem solving. Most striking feature of the book is the rich set of TOOLS/METHODS that can be used at each step of the problem solving. Another important aspect is the format of the book, there are lot white space available in each page of the books which helps reader to actually write down what is important for him/her.

How to Solve it By Goerge Polya
"Heuristic" approach of problem solving proposed in this book is a must for all problem solvers in their toolkit. I think Polya makes mathematical thinking available to all and has proved in a excellent way that mathematical approach can be used to solve any problem at hand. Simply the best book I have read which makes mathematics looks easy, just don't miss reading this

The Thinkers Toolkit by Morgan D Jones
"Hit and Run" approach - the most common response when a brain is faced with a problem is to find a solution and get rid of it. James in his book calls this "Satisfying" or "Hit and run approach", brain scarifies concepts for getting into solution quickly. This weakness of brain can be over come by using some tools. Morgan spends some time talking about general concepts of problem solving and decision making in the first part, in the second part he lists 14 tools and then more ideas on fine tuning the problem solving process.
