When I feel blocked in beginning a project, I find that thinking backwards from the goal sometimes helps me get started. Beginning from the end result and noting the steps, from beginning to end, clarifies what I need to do. Creativity, in this respect, is helped by structure. Once I identify the steps involved, I can choose a few of them to focus on, and then let my creativity take shape a little bit at a time.
Best wishes in your endeavors. JNC
