There is a false myth that says that tough guys and Femme Fatales are the most flirtatious at the discotheque. And it’s an entirely wrong myth.
What attracts people is a determined personality. And this is often confused with cold and distant behavior.
Suppose you want to attract all eyes; the fundamental thing is to enter the room smiling, maintaining an upright posture, and behaving as if you were at home (but without being a jerk).
How to do it?
All the most successful people I’ve met in my years working in the nightlife world did the same thing; they behaved as if the bar was theirs, not in the sense of showing off but treating everyone as guests.
Be a good host, and you will attract all eyes.
Taking care of people and ensuring they are comfortable makes you irresistible.
