What are the most important papers or ideas that started your research journey?
What were the most important days of your PhD?
What are the most important passages in your thesis?
Where did you do the most important work of your research?
What are the most important skills you’ve developed or built on while doing your PhD?
All of these questions have subjective responses, but are all worth considering. Your work must have important stuff, and even with typos or different perspectives or things that could be changed, it’s far better to focus on what is important and good about your research, than direct attention to things that could detract.
A question with an objective response: who did the work to create a thesis from all of this important stuff?
