Anger is a very negative emotion, It blinds the eyes and shuts the brain, at the end, all it brings is pain.
Don't let your emotions make your decisions, always subject it to reasoning.
Before you react out of anger, think of the consequences. Never do things you will later regret!
People will always offend you, annoy you, provoke you. But never let them control you!
Their actions shouldn't determine your reaction.
One of the remedies for anger is delay.
Take a moment, breathe in deeply before you give a response. Don't act until you are thinking straight.
As Buddha rightly said, "You will not be punished for your anger, you will be punished by your anger."
Anger doesn't solve anything, it destroys everything and always remember, whoever angers you conquers you.
