Everyone should have their charts done (and make sure you know the "real" time you were born, which is based on the longitude. Ex., 10:00 A.M. eastern standard time is about 9:40 A.M. at 80 degrees longitude). It is too important to not do it. David's palmistry book is good to pick up, and face reading books are a must. The four pillars is the absolute must, though. Buy a copy of the I Ching, and get your chart done, in that order, to start. Life begins with the study of the I Ching and your chart.
This is a decent book on the subject, and one's study of Chinese medicine and related stuff will deepen your ability to use what it teaches.
