Just thought I'd share some thoughts:
For one thing, if the answers to the questions are negative, I think you might want to rephrase them in the positive.
You may want to deal with your doubts since it may hinder the paraliminal. By the way, how are you choosing to apply doubt on your being able to accomplish as goal, so as to call it self-doubt?
I suppose if you want to overcome your self doubt, here's something to think about: What would happen if you were to doubt your self-doubt? Think about it for a moment, And as you do, notice whether you feel better or if the self doubt neutralizes.
just my 2 cents
