The guys that get laid are obviously the ones that women are attracted to, but there is another component at work as well. That component is the trust factor. How can you develop trust rather quickly so that you can f*** the girl rather quickly?
You asked her if she wanted to grab coffee. Then you asked if the time worked. Then you asked if the place was okay. Then you asked if she'd prefer tea.
Four questions. Four chances for her to say no. Four signals that you're terrified of making a decision.
Plan it. Pick the place. Pick the time. Tell her where to meet you. She'll either show up or she won't.
Either way, you look like a man instead of a scared little boy.
