The writing process involves, creativity, imagination, structure, editing, drafting, revisions, reflecting and it aims to be thought-provoking. There will always be challenges on any given writing journey and there are numerous ways of improving the text after the first draft.
More often I would say go with your gut feeling when a piece of writing is not yet completely coherent. I know this from when I submitted my dissertation, once proofreading was completed, the conclusion was an element that needed more time to review. If I had the opportunity to change or review any part of the dissertation it would be the conclusion of the dissertation.
Despite how challenging the writing was, I really enjoyed learning, reading, researching, connecting with people and discovering new knowledge and insights. Tutorials and supervision are also a crucial element of the process in validating one’s theories, approach and articulation.
