Your one job today for your writing: Focus on your process. What is working in terms of of how you write. If you worry less about your outcomes, and more on optimizing quality processes, you will, paradoxically, have better outcomes.
So today, have one writing session: 15 minutes, a half hour, or 45 minutes, during which you "observe" your habits, processes, way of approaching writing, and your thinking. Observe what facilitates writing, and what gets in the way.
