Be early for your viva.
Be early so you can take a breath or two and appreciate these last moments on this side of the milestone. In one moment you’re working towards your PhD, getting ready for your viva – and in another you’ve passed through the discussion, responded to all of your examiners’ questions and you’re on your way to completion.
Viva discussion can be deep and engaging, and you may not even notice the event unfolding. Afterwards you could be on a high or tired.
So be early: notice what you feel like, remember what you’ve done to get this far and take a few final breaths before you are Dr Someone.
