Your past actions or deeds determine your present self and your present situation , and your present actions determine your future situation. The past tells us what decisions worked in particular situations and what didn’t. This can be useful when taking decisions today in similar situations and thus making life easy , peaceful and successful. Certain events from past inspire us, motivate us .Thus, the main reason behind why we should study History is to ensure that we don’t repeat the same mistakes as our forefathers as history repeats itself.
If we learn from our past deeds , our future will be good. Like , if a child learns from his failure in exam and works hard for the present coming exam then it is sure that he will secure good marks in his exam.
