As everyone knows, those who reject their past will not find their future. Equally, those who do not accept where they came from, deny themselves their future journey. Agreeing with the previous posters, history has a tendency to repeat itself. We have had 2 World Wars, a number of civil wars around the world, and it seems as if humans simply go on making the same mistakes over and over. However, these incidents only happen when we refuse to see the signs of the time, and when we pretend that things can fix themselves without the intervention of common sense. This being said, one must always face forward with a caution not to follow the unhealthy patterns of the past.
