In her altogether wonderful Washington Post conversation, New Yorker staff writer Susan Orlean this reality-check:

You only are having trouble writing because you don’t actually yet know what you’re trying to say, and that usually means you don’t have enough information. That’s the signal to walk away from the keyboard, think about what it is that you don’t really know yet, and go do that reporting.
