This was one of the most valuable books I read all year. It has certain problems (one of which is the author's inability to use a comma!), but this book will teach a patient reader anything and everything about how to think creatively.
Some notes/reminders:
* The mind as a self-maximizing memory system that grabs set patterns and is resistant to letting go of mentally acquired patterns and conceptions.
* Sequence of arrival of information and how it locks in certain conceptual frameworks.
* Logical/vertical thinking (where every step has to be judged/right), vs lateral thinking where you embrace being wrong on purpose, deliberate restructuring of inputs and information, etc.
* Use of the made-up word "PO" as a conversational/cognitive trigger for lateral thinking, both linguistically and conceptually.
