Believing new things homework clarification


In the homework for Believing New Things, after the positive thought download, number one is to write the new sentence I want to believe. My question is, is that sentence supposed to be the same sentence every day? It makes sense to me that it is the same sentence daily – I get that repetition is key. My understanding is that I don’t want to be rote in answering how it feels. That is going to be fresh and new every day. But the actual belief that I am growing to believe, is the same sentence every day, right?
Thanks!
