Anger doesn't solve anything. It builds nothing, but it can destroy everything.
Life is far too short to let anger ruin your day or cause you a lot of time spent brooding over this emotion. When you hold on to anger from the past you are saddling yourself with unnecessary burdens as you work your way through life, and this anger will drag you down and keep you from enjoying each day to the absolute fullest. Forgiveness is the antidote to anger but too many people have never learned how to forgive and let go of their negative thoughts and emotions. In the wider picture a moment of anger is small, but the impact that this destructive emotion can have may be very far reaching. True forgiveness means letting go of all your anger and wiping the slate clean for a more promising future.
