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