What are your viva dreams? What would you really love it to be like?
Two hours or less? Great, smiling faces as you walk into the room? Examiners gushing praise at you? No questions?! No corrections?!
Some of that sounds nice.
But what can you really do about it?
What are your viva goals? What are you practically going to work towards?
Being prepared for the day? Presenting a confident, capable researcher to your examiners? Being prepared to listen and engage with questions? Showing your examiners what you can do well?
A dream can inspire and motivate, but could be difficult (or impossible) to work towards.
Set goals instead: figure out what you can do, then make it a reality.
