Fully agreed with the conclusion. If one continues to get angry with the belief that what I am doing is right, anger is just likely to extend like a chewing gum instead of shrinking (getting less). Therefore, the scientific way to deal with it is to first acknowledge is what is happened is wrong. When this feeling persists, anger is likely to subside by some degree, every next time it bursts out from you. I got to know about this way of managing anger from here:
