To add to OP: It helps to pay attention to physical symptoms of stress as well. If you find yourself constantly tensing your jaw or your shoulders, take a moment to focus on relaxing your muscles and breathing. Overcoming negative automatic responses just takes consistent practice.

To further add: being able to acknowledge an emotional response to a situation and then divert to objective thinking is a superpower. Sustained anger, sadness, or fear will quickly drain your energy and leave you unable to act with intent.
