I will treat my PhD studies as I have treated my work--I will show up every day at 8:00 or so and work through until 6 or so, taking a break for lunch and of course lots and lots and lots of coffee. I will plan to treat the PhD like it IS my job--because until its done, it IS, and give it the same level of serious commitment and concentration. It might sound daft, but I am not planning to slouch about the university in track pants and trainers--but wear sort of business casual stuff, because for me, if I am dressed to work like a professional, I am going to carry on like one.
