Think of your thesis as a star. It shines, it’s powerful. It’s there because you’ve set it out in the cosmos of your research field.
Somewhere in that vast space are the works of your examiners. They’ve done more; their contributions might make constellations. Patterns of lights in your discipline.
Don’t think negatively of yourself by comparison. Instead, just look at the constellations. What do they look like? What does a constellation tell you about what an examiner thinks?
And what might your thesis-star look like from their constellation?
