My PhD supervisor says that I am overly curious and spend too much time studying lots of different area. However, he does say I am generally doing well and on the right track.
I am usually keen to meet new researchers, and I also spend time helping other PhD students to understand papers, even if they are not directly related to my field. I tend to keep studying a topic until I feel I fully understand it.
This has led my supervisor to believe that I am not working up to my true potential and just moving among areas too much. I have asked him directly and he says I just need to focus on one thing at a time, which I have started doing. I am just curious as to whether it is normal for PhD students to change and be immersed in different topics frequently, or am I just thinking too much? What strategies can help with staying more focused?
