Anger is good

Good thing because it can provide you motivation, inspiration to do something good, and it can fuel you with high energy level. At times, nothing acts as a good motivator than anger. Anger of being disrespected, anger of being hated for your weakness , anger of being rejected in something because you were not good in something - certainly burns a strong desire in you to do something great that the world will wish they would be you, every body would be talking about how awesome you are. All right, that one part of anger.

Anger is bad

The fuel of anger could also burn you negatively if you do not have the ability to control it. This again creates anger inside you which in turn could again harm you and this goes on in a cycle until you realize it and struggle to stop it. Till then you might become totally weak to fight, psychologically. Excessive anger could also cause physical problems like blood pressure, heart disease, obsessiveness, lack of concentration in anything. (Encyclopedia of Psychology)
In anger, people often say too much to others and regret later. There is a problem of social rejection for their behavior.

How to control anger

William DeFoore, an anger-management writer, described anger as a pressure cooker: we can only apply pressure against our anger for a certain amount of time until it explodes. Don't try too hard to control your anger. Frequently release your anger time after time because if you accumulate anger inside, it's going to explode at some moment. Anger is a healthy emotion.

There are these tips that can help you control your anger, and take only advantage out of it.

1. Get angry time after time

   Getting angry is so much important in life. It's as important as feeling other emotions like love, interest, hobbies, being happy, etc. A person who gives time to all his natural emotions is a relatively healthy person. Imagine a person, who never gets angry. One part of his life is totally gone. These are the emotions that makes the life of a person interesting enough to live it. Otherwise what is the achievement of life. Nothing. You born, grow up, live, think what other people put to think in your sub-conscious, get controlled by your hormones, do different stuffs produce children and die. So get angry.
   

2. Get a basic understanding of how life works

   Ignorance is bless my friend. But if you think that you know a significant amount of psychology, learn it completely. In that way, you can control being too much angry for something and manage your behavior. Normal people undergo so many difficult situations, and they get out of it normally, without having any psychological ill-effect. The reason is, they do not over think. Over-thinking is becoming one of the major cause of psychological disorders now a days as ability to think is increasing the thinkings are not managed properly. A person who is able to imagine is more likely to fall in trap of the loop-hole of over-thinking trying to imagine every possible consequences of a certain act. Being foolish is sometimes much healthier than being over-smart.
   

3. Take frequent break from your life

   Its the defect but of age, that people are not able to make a free time for themselves. Always taking tensions day and night, always being obsessed with the thinking of success, always thinking thinking is not what our mind is made for. Its also for relaxation. Take complete break from your life, go to a totally different place, relax, and do not think a bit about your work, or what you do, or about any problems these places might have. Just think good things, do not be hard on yourself, spend money on things you have always wanted to buy or you are fascinated about. Go to dance, sing, talk to people, flirt what ever that you like to feel better. But do not do anything that you get embarrassed later which in turn will increase you stress.
   

4. Express your dis-satisfaction

   This is very important. Make a network of friends, may be with similar problems, similar age and habits. Frequently talk to them and talk what ever you like about your problem. You might not believe but it works like an effective medicine. An outside perspective can help you focus on the actual problem and work on it. Otherwise, you are lost in your emotions and you can't even recognize the actual problem.
   

5. Adopt a hobby

   Diverting your mind is a very good way to remain healthy, considering uncontrolled anger as a disease. Get a hobby for example, get physical exercise, start blogging in a topic, start making some designs, or compose poems/songs etc. Adopting something you are better in doing will help you be happy. How your mind works is that, until things are good, everything will work great. Once problems start appearing in your life, everything is messed up. It's not actually so in real but your mind projects that way. Being happy is the best way to keep everything in order. Don't do something that will give you the feeling of failure for the rest of your life. Always give priority to things that you are good yet. Remember that other people might be better and there is always of chance of loosing.
   

6. Be Flexible

   In-flexible person are generally very great in the early part of their life, until they fell in the trap of some problem, which arise because of their mis-concept. Once they fall in the trap, its years before they recover from their disease. The need to change, cause conflict in them whether to believe what they have always believed, or to change their concept and adopt what seems to be right at that moment. There is no remedy for the conflict inside your mind. It sucks all you mental computation power, like a computer, making you tired, confused, and you will feel anger but you don't know whom. Anger could also be decreased by saying bad things to the person, but in this case there is no person.
