These are a list of writing "strategies" that can be helpful when writing (e.g., to get going or to get unstuck). A meta-strategy is to jump between strategies: Feeling stuck? Then pick another strategy. Each strategy can be applied at different granularities, e.g. for an entire book or paper, or chapter or section, or just a subsection or paragraph. Different approaches may work better for you in different phases of a project.
In all cases, remember to avoid premature optimisation; re-writing and editing comes later.
Lastly, always be writing. Writing is like a muscle; being comfortable with writing takes practice (and good writing takes even more practice).
