For the MIT Challenge essay, can I write about a research experience i didn't enjoy?

Last summer I did research in a chemistry lab, and I didn’t really enjoy it so much. It felt really repetitive and I didn’t feel I was doing a lot that would be useful. This summer I’m doing research I enjoy a lot more.

So for the MIT ‘Challenge you’ve faced or something important that didn’t go according to plan’ essay, is this a good topic? Does it reflect badly on me at all?

I think if you write about how you changed from the experience and/or if you did anything to improve your research experience it would be fine! I would also discuss your current project a little bit.
