Hello, I would like help deciding my dissertation topics, and I am considering various options. The work is very stressful, and I feel like I am heading in the wrong direction. Every time I consider a topic, I ask myself: Is this choice appropriate? In the past, I have felt that the topics I am considering will lack importance.

I am in need of some interesting and relevant dissertation topic ideas, as I am a student and a considerable amount of work has been piling up. Please recommend topics that are achievable and a bit out of the box.

Every day for the past few days, I have been generating new ideas, but none of them seem plausible because they are all completed by someone else.
I would much appreciate the ideas of others who have previously completed their dissertation. Thank you for your assistance!
