To understand where were going and why look back →

I think our life will seem very different when we reach the end and look back.  All that we have explored, learned, and have done, will change us. Will we even recognize our beginning self?

We will see the whole of our life very differently than we did as we experienced the parts. The beginning, the journey, and all of the related circumstances to the journey will be clear, for the first time.

It will be the first time we see the past through the prism of all our experiences and that knowledge will let us know what really happened.

I have always loved this quote by T.S. Eliot: 

"We shall not cease from exploration, and the end of all our exploring will be to arrive where we started and know  the place for the first time".

Soren Kierkegaard seemed to be saying this when he said:

"Life can only be understood backwards; but it must be lived forwards."

In the Essay Section of this website I wrote an article titled Reflections on Life . In that article I said:

"There is no one whose story I am as familiar with as my own. The same is true for you. This seems so obvious, but then what surprises me a little is how I see that story differently almost every time I tell it". It really is different when you look back."

Our conclusions change because we see through the filter of experience.
