Face Reading gives us an ancient system of reading character by looking at Facial Features. Face Shapes are always the hardest to interprete in so far as most people have a combination of different shapes, not just a clear geometric shape. Here are some psychological meanings when the face shape is just ONE shape:
Triangle (President Obama): person is a visionary, also thinks fast, moves fast, may drive fast.
Rectangle (my face): College professor type, language and meanings are important.
Circle (round): Great for Sales person - looks like a baby's face, and so folks would be very trusting.
Square: (Winston Churchill, WW II): general, top executive, leadership face.
Bucket: (lower area is wide/full, forehead area is smaller): may be moody and/or emotional
You always look at the complete face for an accurate understanding of the person you are analyzing. For more information please see my book, Face Reading - How to Know Anyone at a Glance (the brown book) on http://www.facereading1.com/.
