Negative Emotions are death of intelligence

Ever been angry at something or someone and regretted after sometime. It happens every time. In every situation where we become angry if instead we maintained our calm then we could have handled the situation much better. 

Negative emotions are shortcuts that evolution has created in our brain to protect against  awful stupidity. They are our shortcut to correct thinking process. 

So when you feel some negative emotions like anger/ sadness/ anxiety, these are triggers in our brain to to take a quick boiler plate decision. But we should instead use them as trigger to think  further and work further on solving a particular problem. 

Angry: If somebody does you wrong you get angry. But most of time shouting or physical violence only causes you harm and instead of solving only increases the problem. Instead if you react calmly you are much more likely to solve your problems. 

Here I am not advocating you to reply back. If  you really need to slap or abuse, please do so. But don't do so without thinking about consequences.

Anxiety: We face anxiety whenever we face important moment, a big presentation or interview. It is as if our brain wants us to sabotage us at most important time of our lives. In such situations imagining that you are not going to fail reduces anxiety. And work on whatever weakness that may cause you to fail.  

Our negative emotions are triggers to act hardwired into our brain for shortcut decision making .

But we have to remember that they are not license for rash decision making. Instead these are the times when remaining calm gives the greatest benefit.
