Intentional model: from which letter should I start?

Hi! Iā€™m French and I joined scholars this month and my first priority is to master the model. I’m struggling a little bit šŸ˜‰ but I’m hanging in there. I don’t have a specific question to ask about a model (I’m saving that for my personal coaching appointment or the live “mastering the model”) but a general question:
When I make an intentional model to improve a situation, what should I start from to build it? The feeling I want to feel? The result I want? What is the most efficient?
Thank you so much for your help!
