I asked one woman friend of mine "why did you go out with him?" and she replied: "because when I looked at him he kept eye contact with me."
When I recall the very successful people I have had the pleasure of working for in the corporate world, I remember that they all maintained eye contact while speaking to me. When you watch somebody successful being interviewed on TV, like Scott McNealy of Sun, you notice that they never look away from their interviewer's eyes and they rarely blink.
You are approaching a chick in the hall as you walk towards each other. When should you look at her? (Her eyes, silly. If you look at anything else, it's over.) I have tried all combinations. If I wait until the last instant, I either find she is not looking, or, if she is looking, she quickly looks away. If I look at her and she looks at me and I look away, then she never looks again. Then I tried something bold and decide I will look at her eyes the entire time. To my amazement, she gazes like a deer into headlights. Never breaks eye contact. So I decide to try this little experiment.
