The document discusses the high non-completion rates among graduate students, particularly in thesis programs, attributing the struggles primarily to difficulties with writing rather than lack of ability. It emphasizes the need for proper support and guidance in writing, as graduate-level writing is significantly different from undergraduate writing, requiring sustained effort and a shift in strategies. The author suggests approaches for supervisors to better support their students, including educating them on the writing process and employing motivational techniques to manage anxiety and procrastination.
