How do you get a woman to change her mood?
The easiest way is by putting her into the right environment. Then you get to kick back and let the environment do the work.
Men create (or attempt to create) seductive environments for women all the time:
They dim the lights and put romantic music on at home
They take girls places they hope will set the proper mood
They switch from one venue to a more intimate one as things progress
Yet for all this awareness, a lot of guys have a blind spot a lot of the time to the influence of environment.
The environment you're in plays a BIG role on the mood of your woman.
The more seductive the environment, the less work you must do to maintain a seductive mood within her.
Thus, the better a job you do managing the environments you find yourself in with women, the more effective a seducer you will tend to be.
