Believing new things in advance – "priming-the-pump"

My new belief for this month’s homework is: I will make 100K in 2020. Basically, it’s just been a lot of thought work because while I’m working towards it, for the moment, I’m already doing all I can. Is this still helpful or did I miss the boat this month? I know the answer, it’s is yes if I feel like it’s been helpful. However, I haven’t really had to take action, which I know will feel very different. I feel like I’m “priming the pump” so-to-speak. How helpful is this in your experience?
