Over the long arc of your career, you will complete many research projects, one often leading to the next. Research is an archipelago, not a single island. Your goal should be to build a career piece by piece doing good research. A professor once shocked me when I was a graduate student by saying, “Hopefully, your dissertation will be the worst thing you ever write.” Now I give the same advice: Our goal as scholars is continual improvement. Do the best job you can on your dissertation, defend it, publish it in some form, then move on.
Yep. That’s the goal.
More good advice here for those of you who’ve crossed over the river and are on the tenure track.
