Sometimes I think that we get so caught up in the day, that we forget to think much about the one that came before. Yet, our past does, quite regularly, inform our future, and realistically, we should never want to ignore our past, as it has helped shape who we are today.
When we do have the time to reflect on our lives, we often tend to push aside thoughts about the aspects of our being that did not go as well as we hoped, and we tend to ignore (or worse get angered by) the people in our lives who treated us as less than we would want to be treated.
Yet, even those who had a negative impact on our lives can to be remembered for the positive learning we took from them. There are even times when we can learn more from those who were thorns in our side than from those who we consider close friends or family.
Regardless, all our experiences (both positive and negative) come together to help make us who we are today. While it is true that our past does not define us, we should embrace the fact that our past helps us define for ourselves, who we will become in the future.
