The importance of the past

Past, present, future ______
That's our life.
The moments that are past are called the past.
But it would be wrong for us to think that the past has no value or that we don't need the past, because the past is a hidden force in our lives.
The past is the history of our lives.
Happiness, sorrow, good-bad, victory-defeat, everything is a book written in the past.
Just as a tree clings to the ground to protect its own existence, so does the land of the past and our devotion.
By standing on the past we build the present.
We build the present by learning from the mistakes of the past.
The past is an essential part of our lives.
We should not forget the past but build our lives by learning from the past.
