Once again, good luck! You were able to explain the position well here and your current job in other threads, so I think you are prepared.
Here’s a breathing exercise to reduce anxiety. The article says it was developed by Japanese zen masters and later used by Navy SEALs. It’s known as box breathing because the breath is divided into four equal parts.
1. Starting with empty lungs, breathe in for 5 seconds through the belly
2. Hold for 5 seconds
3. Breathe out for 5 seconds
4. Rest for 5 seconds
Repeat for 3 minutes or until you feel calmer. You can change the length of the steps, as long as the ‘sides’ are even.
Hope you find this one useful!
