Don’t trust that you’ll be lucky and that somehow things will work out at your viva.
Instead, trust in the process. Vivas are governed by regulations, expectations and the culture of your department.
Trust in your examiners. They’ll do their homework, be well-prepared and be offering you the chance to engage with relevant and realistic questions about your thesis and more.
Trust in your work. You’ve invested years in it, after all, both in your research and your thesis. Trust that after all of that effort, it’s enough.
Trust in yourself. You’ve invested years in you too! Trust that after all of your work and determination, you are enough.
You are enough. You don’t need to be lucky.
