ANGER, FEAR IS THE ONLY TRUE ENEMY
Anger is never without an argument, but seldom with a good one.
ANGER, ANGER IS WITHOUT AN ARGUMENT
Anger becomes limiting, restricting. You can't see through it. While anger is there, look at that, too. But after a while, you have to look at something else.
Experiencing sadness and anger can make you feel more creative, and by being creative, you can get beyond your pain or negativity.
A little anger is a good thing if it isn't on your own behalf, if it's for others deserving of your anger, your empathy.
