Here's the exercise I use, based on help from my dating coach, I call it 'planting';

Go out to a mall, bar, or somewhere women walk around, and approach some (non-seated) woman with the sole objective of being the last one standing at that spot. Open her, plant your feet in place and keep talking, make up bullshit, say anything etc you have to etc., but absolutely refuse to walk away from that spot. You now own it, and she must be the one to leave it.

Stand there. Lean back on a wall, pillar, table etc., helps too and looks confident (called anchoring by Mystery and very useful in all pickup situations). You own this spot, not her, and she is the one who must walk away!

There are only two possible conclusions now: get her number, or she walks away.

99% of uninterested women will expect you to give up, puss-out, turn tail and walk away from them. That no longer happens. You will be amazed how that refusing to walk away presents a very, very strong frame. In some cases, it almost becomes a battle of wills, like a staring contest, and this is one you are going to win.

(In bar situations its also far better to force her to leave than to do the 'walk of shame'.)

Also, do not shuffle around, or pace around the spot etc, keep your feet firmly planted in place. I was bad for doing this, and it looks really nervous. Now I stay planted. Planted. It really relaxes me and improves my confidence while I'm talking. Lean on something if you can.

On one of my first times doing this I walked up to a beautiful, but bitchy looking, tattooed woman in a clothing store and planted, leaned on a nearby clothes tables, opened and bullshitted for like 20 minutes. She turned out to be really nice, but she wouldn't walk away! And I wouldn't! So finally we're still talking and she takes out her cell and texts her husband to come rescue her. haha! She was just too nice to walk away. Finally, the husband comes, sees me chatting up his wife (WTF?!) and I stay fucking planted. I'm nice, I greet him with a handshake, keep talking to him now and refuse to move. Eventually, he betas out and leaves with his wife. Couldn't believe it. My dating coach breaks out laughing.

Man, 'planting' and the mindset that you're getting the number or she's walking away is an awesome confidence builder and a really big help in picking up. When you know there are only two outcomes, and pussing out and walking away is not one of them, its a big confidence booster.

Do this several times and you'll get the idea. Ejecting too early will never again be a sticking point. Hope it helps, and I want you to reply back when you've done this with what happened and how it feels!

(I'll post an advance lesson on how to do this if the woman is seated later, if there's interest)

*EDIT: There seems to be some confusion about this, so let me state that Planting is an *exercise to overcome the problem of premature ejection, not a rule for pick-up. After guys learn to stop ejecting too early, then it becomes time to learn to recognize when a set isn't going anywhere so they can eject and move onto better sets. **
