Quote from the movie "Seven Days in Utopia" which is a golfing movie. The quote was used to aid the golfer in "creating the shot". See it, Feel it, Trust it (SFT).
Jewell Shihan's analogy; when practicing keep all the points in mind. Create a picture/vision of what you want to happen. With your partner train slowly and focus on gaining a "feel" for what you are doing. Once you have focus, and are able to achieve the necessary movements to accomplish your goal, you will be able to "Trust" your abilities, which will strengthen your confidence.
