STAY COOL: Anger is a condition in which the tongue works faster than the mind.

Never do something permanently foolish just because you are temporarily upset.

Anger is a response to feelings of unhappiness, which in turn arise whenever we meet with unpleasant circumstances. Anybody can become angry and that is easy, but to be angry with the right person and to the right degree and at the right time and for the right purpose, and in the right way, that is not within everybody's power and is not easy. According to Buddha - Holding on to anger is like grasping a hot coal with the intent of throwing it at someone else; you are the one who gets burned. Lets read a motivational story :

There once was a little boy who had a bad temper. His father gave him a bag of nails and told him that every time he lost his temper, he must hammer a nail into the fence. The first day the boy had driven 37 nails into the fence. Over the next few weeks as he learned to control his anger, the number of nails hammered daily, gradually dwindled down. He discovered it was easier to hold his temper than to drive those nails into the fence.

Finally the day came when the boy didn't lose his temper at all. He told his father about it and the father suggested that the boy now pull out one nail for each day that he was able to hold his temper. The days passed and the young boy was finally able to tell his father that all the nails were gone.

The father took his son by the hand and led him to the fence. He said “you have done well, my son, but look at the holes in the fence. The fence will never be the same. When you say things in anger, they leave a scar just like this one.” You can put a knife in a man and draw it out. It won’t matter how many times you say I’m sorry, the wound is still there. Make sure you control your temper the next time you are tempted to say something you will regret later.

You will not be punished for your anger, you will be punished by your anger.
