I used to be very easily agitated (mostly being too judgmental) or even got angry when facing difficult situations. Things had improved a great deal since I practice mindfulness whenever and wherever I can, especially for the most challenging past five years.

"When you get angry, go back to yourself, and take very good care of your anger. And when someone makes you suffer, go back and take care of your suffering, your anger. Do not say or do anything. Whatever you say or do in a state of anger may cause more damage in your relationship.
If your house is on fire, the most urgent thing to do is to go back and try to put out the fire, not to run after the person you believe to be the arsonist. If you run after the person you suspect has burnt your house, your house will burn down while you are chasing him or her.
Whenever anger comes up, take a mirror and look at yourself. It is very helpful to see yourself in moments when you are angry. It is a bell of mindfulness.
You need only to breathe peacefully, calmly, and smile mindfully.
Smiling allows the energy of mindfulness to be born in you, helping you to embrace your anger."
入息,我觉知我的入息。
出息,我觉知我的出息。
微笑,我觉知我的怒气。
微笑,我释放我的怒气。
