The creation of great content (whether a book, journal article, dissertation, or something else) involves many stages. These stages include: concept creation and formulation, initial research or investigation, the actual research, gathering information and data, outlining the communications, writing the first draft, revising your writing, feedback from others, additional revisions, final checks, submissions, and release or publication. Revising your work might be the most crucial (and overlooked) step in the process.
Some may view it as drudgery. “I did all that research and writing and now I have to check the grammar!”
