Anger, disappointment, sadness, and all such negative emotions can't be erased, but they can be evaded. Calming yourself down when you're frustrated is, of course, more easily said than done. However, by preparing in advance, you will find that you have control over the emotions rather than the other way around: 1. Do not suppress your emotions 2. Avoid circumstances that trigger unwanted emotions 3. Take care of your mind and body 4. Find a healthy outlet 5. Chase negative thoughts away 6. Above all, be positive!
