"Razeghi's self-help text is designed to assist the everyday genius in finding those 'ah-ha' ideas like those Albert Einstein and Thomas Edison came across in the past. Razeghi presents his thoughts in a straightforward, user-friendly manner." --Publishers Weekly, February 25, 2008

“This book provides a very clear insight into the way people have new ideas and suggests practical steps that can be used. The approach is different from the formal tools of lateral thinking but equally valid."
--Dr. Edward de Bono, Originator of Lateral Thinking,
Founder of the World Academy for New Thinking^TM and author of 67 books

“The Riddle is a remarkable gift cleverly wrapped in a “must read” book. Razeghi thoughtfully awakens and emerges us in that “eyes wide open, believing is seeing, blissfully ignorant” state of childhood so desperately needed in our world today. As “innovation” and “creativity” emerge from their awkward adolescence, The Riddle is not just a right of passage surprise party for your brain but a compelling travel guide for your eager neurons and creative juices.”
--Thomas Stat, Relationship Designer, Innovation Alchemist
