I'm a 3rd year Ph.D. student in an engineering discipline, and I realize that I am better at starting projects than closing projects. By closing, I mean that the work gets published either in a good journal or a top conference. I currently have 3 projects on the side (each of them started as a course project or a fun side project) apart from my thesis work. My advisor is flexible with this, but at the same time he would prefer me to invest all of my time in my thesis work (which is completely reasonable).
Given that I would like to continue in academia after Ph.D., I would like to hear tips and tricks on how to be a good closer. Should there be a restructuring in the way I think about publishing?
