A very nice article on Insider Higher Ed points out that many people need to reconsider how they view writing. Instead of seeing writing as the work that you do after you’ve worked out all of your ideas, writing should be seen as part of the cognitive process itself.
When I ask people to describe their writing process, what often surfaces is the idea that writing is what happens AFTER they have read everything there is to read, clearly and thoroughly worked out an idea in their heads, and have large blocks of time to empty the fully-developed idea onto the page (or into the computer). In other words, “writing” is simply the physical act a scholar engages in after she’s gotten everything figured out internally.
So, instead of waiting until you’ve done “enough” research (which, by the way, never happens) before you start writing, think of writing as a key way in which you process your research and begin formulating your ideas.
