When ever I listen to a Paraliminal I answer Paul's questions that becomes my affirmation of intent. I write my goals considering the rules of affirmations and when think of my goals they are in the form of an affirmation as a result. I'm not one for using affirmations as a mantra since they usually raise inner conflict I find it easier to use the Feeling Exercise, Inquiry Process or Sedona Method when I find myself voicing limiting ideas.
One of the most powerful things I've discovered that works best for Paraliminals (and in many areas of life) is detachment. Do it, let it go, see what happens. The biggest block is the underlying anxiety that need to get it right or work at it perfectly is what prevents one from getting optimal results.
