March Homework Belief

When writing our new belief, do we start with the ultimate belief or one of the bridge beliefs? If we start with a bridge belief, do we update it as we go through the month as it becomes believable?

For example Brooke’s laddered beliefs that took her from drinking to ultimately never wanting a drink. Would she have put each step of the belief ladder on the daily homework or just started with the final belief and work through what comes up daily about that belief that she has no desire to drink and never drinks.
