It's exactly what everyone needs, but sadly it's other way round. We have a mind that forgets the good, but remembers the bad. Thanks to our memory, we forgiven but never forget and this makes our lives miserable. I wish we could forgive and forget, life would be so much easier. Walking around with that additional baggage of grudge is so difficult.

It is easier to advise someone to forget the bad, but I know how impossible it is to do that. I have been trying really hard to forget some past memories, but they bounce back like those crazy balls with extra force and I end up with a ' I want revenge' kind of feeling.
I wish God had thought about this feature while creating humans. If he had done, the. Life would be so much easier. Good memory in this case is a curse. I hope God listens to me and ensures that future humans have a mind that forgets the bad and remembers only the good.
