What is History?

Today, I am thinking... about History? What it is? Is History important? Why? Is it necessary? Does History change our lives? Can we change History? Are we molded into the person we become, by our active part as we participate in the passing of History?

In spite of it all, I am in the process of thinking, compiling and striving to put "pen to paper" to jot down a thing or two about my life.
