Believing New Things – Positive Thought Downloads

I am working on the Believing New Things program and each day we are to do a positive thought download. Is the positive thought load supposed to be ‘any’ positive thoughts I want to generate or should they be positive thoughts specific to the “sentence/belief” I have chosen?

I am confused about the order of this exercise, do I choose the thought from the download vs. do the thought download in relationship to the already chosen thought?
