This is not a dating book, it is a nation-building book. It is far better for a woman to be obsessed with the man than a man to be obsessed with the woman. If a man is obsessed with a woman he is nowhere close to being productive and fulfilling his mission.
He gets in his emotions, he starts to make mistakes that have a deleterious effect on his outcomes, however, when a woman is obsessed with a man that man tends to have better outcomes and she benefits from those outcomes. Someone needs to love someone more that's the ugly truth to swallow, a man should never get involved with a woman who needs to be loved more than she loves the man. Never love a woman more than she loves you...
-Obsession is good because what comes with an obsession is the focus.
