Life in this world is like a wheel that keeps turning, sometimes on top and sometimes we are in the lowest position. human beings are created with all the problems. One of the things that can be a problem in human life is the memories of the past that sometimes appear in the life that is being undertaken.
A bad past is a thing that humans do not want. However, man is powerless to refuse if there is evil that befalls and becomes a past for him. Anyhow it's happening wailing, regretting it, even crying it will not be able to change the situation that already happened.
A smart person will think of the work of remembering the past as foolish and crazy. remember the sadness of remembering the bad past and the joy of remembering the beautiful period will not return everything. The memories of the past are still the past, never going back a bit. then it arises from adversity and have no more sorrow!
