Key to be happy is to get rid of all the burdon of the past bad memories you keep on accumulating,to forgive people who have hurt you.Believe me when you will do so, you will feel much more lighter and filled with life.If you choose to keep on accumulating the past,it will keep coming back to scratch your skin and make you feel irritated and even more hurt for past mistakes.The only way out is to let things go and move with the flow.
Worrying and living in a stress is a cause of many diseases.So don't let you past screw up your present.Forgive people,don't hold grudges and live with a free mind which leads to free soul.
