Jo-Ellan is an interesting lady with an interesting background, but this book was by and large a disappointment. Much of it is common sense stuff that reasonably perceptive people already know. Much of the book reads like this, (my paraphrase) "this characteristic often means this, but sometimes means this and sometimes means this and sometimes means this, etc,. don't take this characteristic at face value until you get to know the person over some period of time and check out all these other characteristics before deciding what the original characteristic means". I'm sorry but this is way too vague and inprecise to qualify as a "secret tip that will change your life". The book oversells and underdelivers.
