Corrections aren’t a sign you’ve necessarily done something wrong in your thesis. The request from your examiners is a helping hand to make your thesis as good as it could reasonably be, given that your thesis is a permanent contribution to knowledge. They want to help.
Most PhD candidates are asked to complete corrections. This doesn’t mean that most candidates are failing somehow or that most candidates don’t care.
It shows that writing is hard. Writing long, involved texts – books! – is hard.
Practice helps. Feedback helps. Investing time purposefully to get better, of course, helps. Proofreading and editing and revising all help.
And after all of that you can still miss things.
When you’re asked to complete corrections, as you most likely will be, just remember that it’s another part of the PhD process. You didn’t do anything wrong; you now have the chance to make things better.
