Never respond to an angry person with a fiery comeback, even if he deserves it...Don't allow his anger to become your anger.
You can’t selectively numb your anger, any more than you can turn off all lights in a room, and still expect to see the light.
If you are self-aware of what you are going through, you would be in a better position to understand others, and affect people around you.
Confronting your enemy in anger feeds your ego, but diminishes your chance of success.
It's better to anger a bit and compensate with destroying something than evolving hate.
