This moment was created by a collection of moments from the past. It is not an isolated instance. To forget the past is to neglect the reality and cause for the present moment. To neglect the future is to waste the present moment, which is not living in it at all. To not be concerned is to surrender to fate. Surrender itself becomes the fate. Is this fate acceptable? Is it human?
But to dwell in past affects your present, which in turn affects your future. Forget the past but never forget the lessons you learned from it. Live in the present as you never know are you going to see tomorrow or not. No matter what you were in the past, all what matters is what you are now and how you are going to mold your future..
