Positive vs. Negative Downloads


I have always thought of the downloads as a way to get the junk out of my head, and for this reason I’ve always believed that the downloaded thoughts have to be negative in nature. Is this true? I am wondering how and where to fit in positive thoughts that I already have that come easily to me and in what way those fit into the models? What would be the benefit of running models on thoughts that I already think are beneficial? Can I mix up the downloads with thoughts that both serve and do not serve me well?

Thanks for any insight you have for me!
