I made the mistake of picking my first dissertation topic based on what I thought would impress my supervisor. I chose something about the economic impact of artificial intelligence on global supply chains, a subject that sounded serious and employable but meant almost nothing to me personally. For three months, I tried to care. I read the papers, collected the data, and wrote the literature review like a dutiful student. But my heart wasn’t in it. Every sentence felt like dragging a heavy stone uphill. By Christmas, I was so miserable that I nearly dropped out, convinced that I simply wasn’t cut out for postgraduate study. The problem wasn’t my ability; it was that I had chosen a topic that had no connection to my own curiosity. I had chosen something I thought I should study, not something I actually wanted to understand.
The turning point came when I finally admitted to my supervisor that I was struggling. To my surprise, she wasn’t disappointed. She told me that this happens all the time, and that the real mistake would be continuing with a topic I dreaded. She pointed me toward a collection of dissertation topics (you can find them here: https://premierdissertations.com/dissertation-topics/) and said, “Stop trying to be impressive. Find something that makes you genuinely curious, even if it feels small.” I spent an entire weekend browsing, not to pick anything, just to see what sparked even a flicker of interest. And then, buried among the lists, I found it: a question about consumer trust in online marketplaces. It connected to my own experience of buying and selling clothes on a second‑hand app, and it felt like a door opening. That tiny spark was more motivating than all the “impressive” topics I had forced myself to consider.
With my supervisor’s help, I changed direction. The new topic was narrower, more personal, and infinitely more engaging. The work didn’t suddenly become easy, but it became meaningful. I stopped watching the clock and started losing track of time. I interviewed sellers, analysed reviews, and built an argument that I actually believed in. By the end of the process, I was proud of what I had produced, not because it was the most original dissertation ever written, but because it was honestly mine. I learned that the topic you won’t regret is the one that keeps you curious long after the initial excitement fades. It’s the one you’re willing to argue with, dig into, and defend — because it matters to you, not because it looks good on a CV.
If you’re at the start of your dissertation journey and worried about making the wrong choice, please learn from my mistake. Don’t pick a topic to impress someone else. Pick one that makes you want to ask another question. Browse real dissertation topics to see what’s possible, notice what makes you pause, and trust that instinct. The right topic won’t guarantee a smooth ride, but it will give you the one thing you need to get through the hard days: genuine interest. And that, in the end, is what saves you from regret.
