It's amazing how much a world class jazz musician can teach you about being spontaneous and in the moment. [My jazz teacher] said "If you mess up or play the wrong note, to hell with it! It's done man, you can't go back to that. The river keeps flowing. Stay in the present!" [He] also once said: "In a spontaneous art form, how you think is EVERYTHING!" (And if you don't think pick-up is a spontaneous art form, try memorizing an entire pick-up, go out and see how much you actually use.)
A lot of guys try to go back and fix their mistakes in game. They will be thinking about what they said 30 seconds ago, wondering if it was good or not, "Was that an attractive thing to say? Did I just blow it? What does she think of that?" Well guess what - it's not what you said two minutes ago that's going to hurt you, it's the mental distraction that is going to put the nails in your coffin! The next time you say something stupid, and you find yourself thinking about ANYTHING that has happened in the past with a woman. STOP. Get back into the moment immediately - get the job done! Your triumphant return to the present will pull her attention to the present as well, and your carefree focus will negate any "mistakes" you think you may have made."
