Being the "Nice Guy" is the absolute worse thing to be if you want to
attract a woman. Being a jerk takes you little bit further because at
least you assume high status (to a sertain degre) but it can only take you
that far.
And only with a sertain type of women. Also ask
yourself, how does it make you feel? Do you want to be an jerk? How long
do you think she will want to be around you?
