Smiling is one of the most important parts of our body language. It is used to display if we approve of something. All the self-help gurus out there, especially Dale Carnegie, encourage smiling as much as you can.

Body language is intimately connected with our thoughts. If we think something our body unconsciously shows it in the movements we make with our facial muscles, body, arms, and hands.

Knowing this, use your smile to your advantage when trying to communicate to a woman. If you want to meet a woman, think "I want to meet you." Then smile.

There is so much more potential to seductive smiling than always thinking "I want to screw you." You can think of anything and use your seductive smile to convey that to the woman you are interacting with.

Women are subtle with their communications and skilled at communicating on multiple levels, something that oftentimes flies past the man's comprehension. Most women will never come on to a man directly, instead they will drop subtle hints like being in close proximity to you, make fleeting eye contact, and anything else save using words to let you know how they feel.

Let them know you are in control of the situation and know exactly what's going on. When they make that eye contact, think in your head "I know you like me and I am going to come over there and talk to you". Then smile. She will get the message.
