Anxious to Action
Concern, anxiety and worry about the viva won’t resolve themselves. It’s not wrong to feel any of these but it’s not good for you to go to your viva with them if you can help it.
You need to do something.
You could ask for help. You could explore a website with thousands of posts about the viva. You could reflect and think about what’s at the root of the problem.
Ultimately you have to do something. Ask, explore, think and then act.
Action can help you move away from anxiety.
