I had several grand ideas about my research question before starting my PhD. Now, I’m beginning to wonder if my question is even rational or if it was just a figment of my overenthusiastic imagination. With my proposal due in a few weeks, I'm swimming in a sea of doubt, doubt, and more doubt. It's exhausting, really. I wanted to work on an interdisciplinary subject, but now it feels like I’m trying to make a smoothie with a hammer. A void of emptiness over my mind...!
