When someone is angry there always is some fear behind it. Next time when you feel anger, instead of anger taking over your emotions, stay present and see what is the fear behind your anger.
When you will know what fear you have, work on the fear, get the solution to your fear. Because when you get angry, the situation starts controlling you, instead of you controlling the situation.
It is rightly said, fearless people are happier people. It is because, in the absence of fear, anger doesn’t arise.
