Forgive = Courage
Forgive your enemies. You have learned a valuable lesson from your enemy. You now have become wiser. You learned to protect yourself. Through forgiveness, you have the courage to look at your enemy in the eyes and say, you can't hurt me now.
Forgive your parents. They did their best to bring you up. They did not bring you to this world and make an effort to mess your up life. Not all can be good parents. At least, they give you your life. Forgive your parents, so your bad childhood will not become an anchor stopping you from living your life. With forgiveness, you now have the courage to live the life that you want to live.
Forgive your loved ones. You love a person but the person does not love you back is painful. A one sided relationship is not fair but life is never about fairness. You love someone is because that person deserve your love. There should be no reciprocity. Understand this and you can love even more.
Forgive yourself. We are not angels. We make mistakes. At times, some mistakes are un-forgiven. Can you counter-weight such mistakes by doing the right things? Yes, you can. By accepting your imperfection, you develop the courage to stare your mistakes in the eyes and learn from it. You cannot undo your mistakes, but you can do many more right things to make a difference. Forgive yourself, so that you have the courage to take the right action.
