Thinkertoys is a workbook designed to push yourself to constantly improve your problem solving approach and creativity.
Part of the book is dedicated to left brain development and part of the book is dedicated to right brain development. Each chapter is focused on a single specific method of looking at things in a new way. The book is written in such a manner that you can read an approach, master it, utilize it then move on to the next over as much or as little time as you need.
After you have developed several skills you can combine the methods to create solutions in even more ways.
This is the number one book that I recommend for all of 2006. It is far more powerful than the excellent sales books by Gitomer, the marketing books by Godin or the relationship books by Sanders... this book is a must read!
Do yourself a huge favor and buy a copy and start reading it
