Scale & Perspective
The viva is one day out of more than a thousand.
Viva prep is important – but takes perhaps 0.5% of the time and work of the rest of your PhD.
The longest possible viva is shorter than the longest work day of your PhD journey so far.
The number of words you’ll speak in your viva will be a fraction of the words you’ve written in your thesis – which is a fraction again of all of the words you’ve written for your PhD.
The viva matters and you have to pass but it helps to put it into perspective compared to the amount and importance of the work you’ve done before.
