I just don't know you very well. Interest Level is a scale that ranges from 0 to 100 percent. In addition to overlooking the woman's Interest Level, males typically overlook the importance of female attitude - a woman's morals and her temperament. Of course it is. Integrity, giving, and flexibility.
Most men know what confidence is, and even know that women love confident men.
The other relationship experts, who come from a female perspective, don't tell men specifically what to do to get this confidence. It means controlling your choices and actions in spite of what your emotions urge you to do. For example, if you're at a dance club, and a gentleman hustles your girlfriend, you know to take it as a compliment to your taste instead of putting a chair over his head. By practicing self-control and not making a fool of yourself, you raise her Interest Level to even loftier heights. Challenge is nothing more than playing hard to get.
