Read this comments and aswer if your agree like I agree with you $.$I think the one thing I need the most when in the box is to only worry about myself and not others. It's important to focus on oneself in this situation is to gain control of your thoughts and feelings to not let external factors take effect.

Another strategy I$\text{'}$m sure everyone is familiar with is to be calm, cool, and collective so handle any situation in the best professional way. If you can control your own thoughts and emotions, you can control anything external.
