Embracing memories is fundamental to one's individuality, but for the sake of peace and a more fulfilling life, it's better to cast them off and start anew, since most of the time, the conflicts people have with each other are based on painful memories people should let go. However, this can only happen as long as everyone is reset to the beginning, with no actions, deeds, or accomplishments to reinforce those memories.
