So there are four things that have helped me the most in becoming a producing writer.
A proper writing tool: Scrivener. Scrivener is a actual writing environment that allows you to work without distractions, to work on the portion of your text that is speaking to you, to write with reference materiel in the same program side-by-side with your composition screen, to move ideas around in bulk with ease (ala the Cork Board) and try out different flows of ideas. It is highly customizable, but the link is to a beta so be sure to export your settings or they'll be undone with each month's update. Ultimately, you'll compile your papers and finish the type-setting in Word, but Word is a joke compared to Scrivener when it comes to actually doing writing. Moreover, my "writing room" is everything I've ever written on my research. When I need to put a paper together for a conference, I can quickly steal my own work from other papers, and dip into my copious bone yard for more things I wrote but hadn't found a place for.
Pilot-light for the writing rocket: Common Place Book. Tons of stuff you'll read is inspiring, seminal, but not really related to what you're currently researching. But that quote SPOKE to you, to your core, to your emotional self. That is the spark that lights the rocket. So record it! Get the citation (APA style), and record the thought. You do this ONLY in paper format. It is nearly useless in digital form. It becomes my prognostication tool: I'll leaf through them at the start of a project and pull ten or twenty and lay them on the ground, mix them up, tell a story with them, ask those authors to speak to my project. This usually becomes my introduction paragraph or two. It provides a greater context to the question I'm writing on day one, moment one. It immediately lends MEANING to the effort. Importantly, I have the citation exactly so I can quote freely and properly cite the reference.
Manage the time, not the writing: A Writer's Time. Writing is endless, projects are not. So you have to put artificial boundaries to the writing and then be consistent each day. Give yourself vacations. Break it into pieces and treat it like an architectural project. Atchity gives you clear methods for working backwards from writing deadlines to program out the work. Then each day you sit down to write, you know what you have to write, and when to stop for the day. It makes the process enjoyable rather than stressful.
Foster the craft of beautiful sentences: On Writing. In addition to his life story, King lays out the state of mind to cultivate and what disciplines to practice to do so. He drives you to aim for your authentic voice, so the work achieves its own soul, and begins to dictate to you what to write next.
