Tips for Staying Calm in High Stress Situations

Physically I try to retain a good posture, lift my rib cage to give more room to breathe. Regulate my breathing so I am taking deeper breathes. Keep my forehead from furrowing.

The solution often for this case is highly situational. Sometimes, the search for a solution will induce more stress. Sometimes the solution is found but the resistance of implementation is stressful. Generally, I try to relate to those involved and see from their point of view, see if they're stressed like I. Trying to replace uncertainty with hope certainly helps.
