One of my friends is about to do her prelims so I've read her proposal and I just watched her practice her prelim presentation. I think what she's doing is really cool, and I've got some serious dissertation envy!
I'm not jealous of her in a negative way, but rather I find myself thinking, "How can I make my research more like hers in the future?" It also makes me think "what if" I'd made different choices in my Ph.D.
I've mentioned before that part of me wishes that I had done local field work instead of flying halfway around the world. If I had done field work here in Big City, her project has all of the elements that I would have liked to include. It's interdisciplinary and just awesome.
Maybe for my postdoc.
