On painting a true and rich picture.........

Learning must come before deciding.   As explained in Chapter One, your brain stores different types of learning in your subconscious, your rote memory bank, and your habits.  But no matter how you acquire your knowledge or where you store it, what's most important is that what you know paints a true and rich picture of the realities that will affect your decision.  That's why it always pays to be radically open-minded and seek out believable others as you do your learning.  Many people have emotional trouble doing this and block the learning that could help them make better decisions.  Remind yourself that it's never harmful to at least hear an opposing point of view.
