1. Determine the topic: First, you need to define the topic of your thesis. This will help you concentrate and avoid wasting time on irrelevant topics.

2. Do research: Do in-depth research on your topic. Consult related books, periodicals and websites. Understand your topic and related research and opinions.

3. Write an outline: Once you know enough about the topic, you can start writing an outline of your paper. The outline should include the main points you intend to discuss and the evidence to support them.

4. Writing in sections: Don't try to finish the whole paper at once. Instead, you should divide your paper into several parts and focus on only one part at a time. This will help you organize your thoughts more effectively and ensure that each part has enough content.

5. Ask for help: If you are still confused, ask others for help. You can consult your tutor, classmates or academic advisers. They may be able to provide new ideas or methods to help you find the direction of writing.

6. Rest and relaxation: Sometimes, you may just need a rest to give your brain time to process the information you have learned. You can try to do something you like, such as walking, listening to music or watching movies, and then come back and continue writing.
