It means that you should STOP doing the following:
1) Having "nice" conversation.
2) Having a few drinks.
3) Laugh and "seem to connect".
And you should START doing the following:
1) Focus on getting emails and phone numbers, not getting
"nice conversation."
2) Avoid "having drinks". Instead have FOCUS (on your
outcome of getting her info).
3) Talk for a minute or two, then tell her that it was
nice meeting her, but you're going to get back to your
friends. Then turn around and say "Hey! Do you have
email?" Take out a pen and have her write it down.
When you're at a club, it's SOOOOO much easier to get
10 emails and numbers, then follow up later than to try
to land the big fish that night. Once you're the super-
duper-mack-daddy-from-hell you can go back to chat and
drinks... but for now get the info!
You'll find that things work a lot better when you're
having a conversation with her ALONE over a cup of tea
rather than in a loud bar full of sexually frustrated,
drunk men who want to show off and fight over women.
