Lacking experience: Writing requires experience. Without sufficient training and practice, the writing skills may not be mature enough, resulting in poor quality. 3. lack of writing skills: writing requires skills. If you don't have good training, you may lack some necessary writing skills, making it difficult for the work to express the author's intentions. 4. Not enough time: Writing takes time and energy. If you don't have enough time to complete your work, writing may become more difficult. 5. Not clear enough thinking: Writing requires clear thinking. If the thinking is not clear enough, then writing may become more difficult. 6. Emotional instability: Writing requires emotion. If the emotion is unstable, it may be difficult to express the author's emotions. 7. The goal is not clear enough: writing requires a clear goal. If there is no goal, it may be difficult to progress. 8. Not enough material: writing requires material. If there is no material, it may be difficult to write. These are some of the factors that can make a novel difficult to write. Of course, there are many other factors that depend on one's writing style and situation.
