It is a common problem to keep the motivation of writing papers and overcome procrastination. Here are some suggestions:

1. Set a clear goal and timetable: break down the paper into small tasks and set a deadline for each task. This will help you manage your time better and avoid procrastination.

2. Develop a reward mechanism: set yourself some small rewards. When you finish a task or reach a milestone, give yourself some rewards, such as watching a TV series and eating a piece of chocolate. This can increase your motivation and enthusiasm.

3. Find a suitable working environment: find a quiet and comfortable place to write, away from interference and noise. Sometimes, changes in the environment can help you refocus.

4. Share your goals with others: Tell your friends, family or mentor your writing goals and ask them to help you supervise and encourage you. This will make you feel responsible and someone can share your progress with you.

5. Make a reasonable plan: Don't try to finish the whole paper at once, but divide it into several stages. Set a small goal every day or week and finish the whole paper step by step. This can avoid excessive pressure and make it easier to maintain power.

6. Find a writing time that suits you: Some people are more energetic in the morning, while others are more creative at night. Find a writing time that suits you and concentrate on writing during this time.

7. Ask for help and support: If you encounter difficulties or lack motivation, don't be afraid to ask for help. Communicate with classmates, tutors or other professionals, and they may give you some advice and encouragement.

The most important thing is to keep a positive attitude and make unremitting efforts. Writing a thesis is a long process that requires patience and perseverance. Believe in your own ability and believe that you can finish this paper.
