Start deconstructing the belonging rubric and come up with the two or three main belonging rubric points you want to focus on your story, and start planning out elements of a story-i.e. plot, setting, character transformation, I would highly recommend you focus on your personal/cultural experiences for a good short story. Make it realistic, authentic and poignant. Start writing-once you start, it is easier to change, to improve-starting is the hard part, but it is an essential process
Best wishes for your creative writing
