There used to be an army recruitment advert on TV years ago where the narrator was telling us how maintaining eye-contact was a key part of being dominant and assertive when faced with angry locals in a war-zone. This is probably obvious but few people do it. Even if you lack confidence, you have to bear in mind that eye-contact is something you can use as a tool if nothing else. Accompanied with a nice smile and you can open a lot of doors for yourself, especially with the opposite sex. The neurotic Woody Allen types who look at their feet all the time are not doing themselves any favours.
I always look angry V_V:
Jam it back in, in the dark.
