How did you feel at the start of your PhD? How do you feel now?
What have you learned since the day you started your PhD? How much have you invested into your research? How many pages have you produced in your thesis? How many more have been edited out along the way?
From day one you work and learn and make something amazing – that leads to one day where you have the chance to talk about it, defend your choices, explain and explore and more.
You got this far through your PhD journey by working hard. You get through the viva in the same way.
