Do not talk about any of your personal (family,
work, money) problems.
Don't act desperate.
Don't talk about anything negative at all. Keep
everything you talk about upbeat and positive.
Don't get drunk. This really turns women off and
makes a bad impression. Don't drink at all or limit your drinking
to a couple of drinks.
Don't try to analyse her problems.
Don't bitch about your previous girlfriends or
ex-wives on how they mistreated you, dumped you, cheated on you,
took you to the cleaners on child support, etc.
Don't pretend to be funny or humorous. If you are
putting on an act, it will come across to her as phoney. Just be
friendly and smile (but in appropriate doses, avoid having a grin
on your face ALL THE TIME, guys that are smiling for hours in a row
look terribly insecure and just plain pathetic).
Don't focus on your health problems or
ailments.
Don't brag about yourself and your
accomplishments. There are exceptions though, but try to be careful
about them. If you really have something impressive to talk about,
you can let her in on it, just try to be real casual about it. On
the whole, women are very good at sniffing out when the male is
trying to impress them by bragging. And if what he is bragging
about is not really that impressive, it's a complete turn-off. So
be careful. Focusing on her and her interests is a far safer route
to take.
And at all costs, avoid these three themes:
politics, religion and conspiracy theories. These are guaranteed to
nuke your otherwise wonderful interaction.
