There are different ways to take this: 1. You can choose to forgive and forget, or forgive but not forget. 2. You can learn your lesson and move on. Experience is a great teacher. You gain wisdom. You can try to take advantage of every failure, because you will find out what doesn't work. 3. People will get screwed many times in life, but still come on top in life. 4. With me? I use such events as lessons to avoid problems or learn how to solve them. Peace of mind is what most of us want.
