Do you feel self critical about your writing? Do you suffer a bit from perfectionism? Writing should be a way to get you to new ideas, but you can’t use it as a tool if you are constantly editing yourself or second guessing. Try developing a practice of free writing. When you free write, you write continuously for a set period of time (say 7 minutes, or 10, or 15 minutes) without regard to spelling, grammar, or even to where you ideas wander. You just keep writing without stopping.
If you free write about your current thinking, you might find that it gets you closer and closer to hitting on the ideas and concerns that will really drive you in your Div III work. The writing itself might not be something you use in the Div III, but it will be useful to your Div III. It will help you know where to bring your writing or your creative work.
