Anger, is largely an inside thing than external provocation. You are provoked or offended to the degree your mind give interpretation to events. Until you learn to rule over the words of men, you will never stop getting upset and overly angry.
What truly hurt us in life, isn't really about the things people say to us but the interpretation we give to their words on our mind realm. Note: If a man's disposition/opinion can rub you of your sleep, then, he surely controls your life. Stop giving mere mortals the driver seat of your life.
Have a blessed day ahead.
Good Morning.
