The past is like a mirror always reflecting our deeds good or bad. This present moment is important as soon it will become the past. And as we cannot glance into our future, it is the present that we need to hold on to preciously, to live as we want to. Even as we step ahead into the future, the present stays with us while the past just fades.
Dwelling in the past would mar our present and eventually our future too. Keeping the past active would in no way help us though we could surely make changes in our present by learning from our mistakes in the past.
The past is like a lesson for us to not repeat our mistakes. Good recollections from the past would evoke positive thoughts in the present and make it worth living. But we need to move on and not dwell much in our past.
Reminiscences from the past must not block us from moving ahead and progressing in life. I have seen that sometimes the memories from the past holds us back from stepping towards success. It invokes in us a fear of failure and we lose confidence in self required to accomplish something.
Finally, I agree with the comments from Ajit and Sreenath that ‘it is life that matters’ and that ‘life is very short’. So, again I would say that it is better to make the most of the present so that there are no regrets from the past in the future…..
