Memories make us sturdy, not feeble. 
Some memories, good or bad, persist forever, but most fade with time. Memories are part of our functioning, given to our bodily systems to derive the purpose of our existence. 
We celebrate good memories and feel awkward when some bad memories reappear. 
We have to live with memories. Simultaneously, we have to manage memories to get maximum advantages in our march toward our goalposts. 
We have to lessen the load of the mixed bags of past experiences and create new stories to get maximum satisfaction. It is like the stories we read. Some good stories influence our minds deeply, also impacting our ways of living. Others do not create niches in our minds. 
In brief, let us use our memories as grounds to build up futures conforming to our dreams. 
When we look back at our own stories from one or two decades earlier, we see a lot of differences. It may be that we have not changed ourselves, keeping pace with changes around us like connectivity. upward graph of the network of information, innovation in all domains, and so on. As a rule, the richness of our experiences gives better returns, applying the principle of compounding.
Memories are an inseparable part of our experiences. But something wrong from the past also continues to retard the process of our moving forward. That is why the four words "be in the present" carry such a vast meaning in everyone’s lives. 
To erase unpleasant stories, we need pleasant stories—not once or twice but again and again. For creating new stories, we have to listen more to our own positive self-talk than the remarks of the outer world, irrespective of our kind of activities. Our self-talk creates courage and consistency to cross the barriers in our ways and to do what others are still struggling to accomplish.
