You Don’t Need To Be Perfect
You don’t need to have done perfect research.
You don’t need to have written the perfect thesis.
You can’t have done every possible task in preparation.
You don’t need to have an answer for everything.
You don’t need to be perfect to succeed in your viva.
Work hard, do your best, find out what to expect, prepare as well as you can.
You don’t need to be perfect: you just need to be you.
