Now that we agree on what attraction is, the next important thing is to be able to know when you have achieved it.
There are specific clues that many women will give when they are attracted; we call these Indicators of Interest (IOIs).
In other words, they make the lethal mistake of constantly over-explaining and trying to “convince” women to be with them. However, if you get easily emotional and upset about the wrong things (small inconveniences…perceived insults…other guys) then, at best, she’ll judge you to be insecure.
The cure is becoming a man who always gets to the point. At worst, she’ll judge you to be an unstable creep.
I don't mind if you guys lose a potential relationship during the comfort stage once in a while, but there's no excuse for losing often early on.
