How much work do you need to do to prepare for the viva? How do you get ready when you have so many other things going on? How do you deal with anxiety?
It’s all about finding a balance.
Balance the prep work against what you know and what will help. See what other people do and what resonates with you.
Balance your day job and family life against the time you need to get ready. Find strategies that allow you to work effectively and fit the work around your commitments.
Balance your nerves against the work you’ve done. Your thesis didn’t appear from nowhere.
Simple solutions can work when you focus on them rather than problems.
