No matter what name we give it -- hunch, gut feeling, sense, or instinct -- intuition remains an alluring but mysterious subject that few of us understand. Until now. In this fascinating and persuasive book, intuition expert Gail Ferguson explains intuition as a specific human sensory system -- a sense just like hearing and seeing, but one that's so unfamiliar to most of us that we don't know when it's happening or what to do with it.Clearly and systematically, Furguson shows how our own innate intuition helps us cope with the unknown facts and unexpected events in our lives -- what she calls "Factors U." To help us develop our intuitive abilities, she recounts dozes of fascinating case studies from her files that illustrate her common-sense routine for using intuition reliably, one which she herself has used successfully throughout her life and professionally for over 25 years.
