Reflect
Take time to stop and think.
Reflect on your PhD. Reflect on the journey. The peaks and troughs of hard work and difficult circumstances that have brought you this far.
Not far to go now. Reflect on what you need to do to get to the end.
And reflect on how it will feel and what you might do when your PhD journey is over – when you start a new one as a PhD, not working to be one.
Take time to reflect before your viva.
