To keep cool, use all the internal tools—this is where they really shine. I particularly recommend the following techniques: Check your physiology often, both for your own sake (it affects your psychology) and for that of others (it will be “caught” by them and will spread). Skillfully handle internal negativity: destigmatize, dedramatize, and neutralize the negative perceptions that may be crowding your mind. Rewrite reality to whatever degree is helpful. To get out of a pessimistic state, find a few different ways of viewing the situation positively. Use visualizations to keep yourself in the right state. For instance, a responsibility transfer could be useful for reducing anxiety.
