To my direct knowledge? Nothing. Except for practice.
Even after graduating college I found it challenging to write anything more than a page long. Not to say I couldn't write, I was just very brief about it and often didn't fully explain my ideas. Lots of assumptions in what others would "get". Also writing even that 1 page would be pulling teeth.
A decade or so of pushing myself to write about anything and everything, it's become much easier. I still have challenges getting started, when I've been on writing break for a while. But when I do "Get going" it flows much easier and at a much greater length.
