This miniature guide introduces the art of asking essential questions. It is best used in conjunction with The Miniature Guide to Critical Thinking and The Miniature Guide to How to Study and Learn. The quality of our lives is determined by the quality of our thinking. The quality of our thinking, in turn, is determined by the quality of our questions, for questions are the engine, the driving force behind thinking. Without questions, we have nothing to think about. Without essential questions, we often fail to focus our thinking on the significant and substantive.
