Consider making two lists as you read your thesis in preparation for the viva.
On one list, make a note of any typos that you find or any sentences that you think need revising. On the other, make a note of anything that you think is good, great or amazing.
After you’ve made your lists put the first one away until after the viva. You’ll find it useful then to help you complete your corrections.
Look at the second list every day on the lead up to your viva. Remind yourself that you have done good work and you can be confident that your thesis has value.
Corrections need to be done eventually. Before the viva it’s far more important to look for things that will help your confidence.
