The path to the past is usually there where you can see it. But trying to spend our energy to travel back there or even to try and live there, doesn't do us a lot of good.
Spending our energy in our days right now in the present moment is a much better use of our energy. We can remember our past, but live in the now.That works. But trying to live in the memories and come back to the present only for a few moments, leaves our lives as dry and dusty as a desert train track.
