Over the years we learn a big amount of lessons on different things. But, what about the history of our country? "Man is the only animal that stumbles over the same stone twice" This proverb is completely accurate describing human beings. some people may think to learn from the past is a mistake, they think we are not in the same circumstances. But that is not right we can see in politics, for example, the people still make the same mistakes from years ago because we do not learn about it. Not everything is indeed about the past. The future and the present are more important, it is our life. However, the past is the first step which everybody has to go through. Furthermore, every action we did in the past can impact the future. Besides, it is not just because of the future. It is also for us as a person. We can understand better the world in which we live. Also, we can develop other abilities and put them into practice. For that matter, knowledge is a powerful tool that not only can prevent wars but also helps us to grow.
