Beginnings are the best & the worst
You know how that undeniable excitement you feel when you start a new project is always followed by: "Okay but like...where do I start?" Yeah, that part sucks.
When you can't think about what to write about sometimes the only thing you can do is write about not having anything to write about. You could mention how you hate it when you don't know where to start, and perhaps follow that up with a sentence about how writing about not knowing what to write about is a good place to begin writing.
And then you get to the third paragraph and realize you haven't actually written about anything except not having anything to write about but it's the third paragraph so are you wrong or are you a genius?
