If you have a particular ongoing behavior that you would like to stop or change, or would like to instill a new bahavior, use New Behavior Generator. When you are self-sabatoging and don't know why, use this Paraliminal.
When you know how to do something (and action or a behavior) let's say give a speech, or dive from the high diving board...but you have internal dialogue or self-doubt that makes you fail, use Automatic Pilot to eliminate the negative self-talk. When you can identify the behavior that is the problem and know that it's this inner talk, maybe from past failures, that's stopping you, use Automatic Pilot.
Another example, let's say you are trying to lose weight and stop smoking. You find that you can stay on track for a while, but then you go back to your old habits. New Behavior Generator or New Option Generator. In this case you are self-sabatoging, but it's not self-sabatoge that's stopping you. In other words, you must be getting some kind of reward out of continuing the behavior, which you may or may not realize. Use Automatic Pilot when it's the inner talk, i.e. self-doubt, that's stopping you from succeeding in a specific task or goal.
I hope that helps!
