Whatever stage you’re at during your PhD, sooner or later you’ll be finished. For a lot of researchers I talk to this seems to come around much, much faster than they thought it would. Sooner than expected they get to their first draft, then submission, then the viva, then graduation.
Just like that, you’ll be done.
So before you get that far: what do you still want to do? What do you have to get done to feel happy with your PhD? And what could you do to make your path to completion enjoyable for you?
