Your PhD could be worth all the hours and money you have invested.
It could be worth a particular job that you’re aiming for.
It could be several papers you can publish when you’re done.
Or it could just be something you did for a while, not that important in the future – something fun to tell the grandkids about one day.
(“No, no, I’m not that kind of doctor…”)
Whatever it’s worth personally now, or whatever it could be worth in the future, it’s worth finishing it well. Take a step back as you near submission to know what you need to do to pass the viva. It doesn’t take much to prepare and there are lots of people who could help you.
Whatever your PhD is worth to you, it won’t cost a lot to be ready for your viva and secure your success.
