I read about this a few years ago and it seems to work pretty well for me.
While your out with a woman, having dinner or whatever, hold up something like a salt shaker look at it and ask “so, what’s your favorite ice cream?” Then, later when you want to get the answer yes to another question, like “you want to come back to my place and see my cool thing a ma jig?” Hold the salt shaker up and look at it again just like before while asking.
Try it and let me know about your results.
