Try to stay in present

Humans are very similar to computer where we can store data

But we can delete some of the past data in computer else in human brain we cannot delete our past memories

Because of our inability to erase past memories, we tend to revaluate events that happened in past

We can easily categorize past events as happy one and sad one

Analyzing the events happened in past is good

It allows us to possibly understand better. What happened? What should we have done better?

Regardless of what we think that we should have done, we can’t do it now. Similarly we can’t go back and find happiness there in our happy events

  

                                  

We can only gain knowledge and experience from those events

Reliving the past can be addictive and dangerous

So analyze past events to understand the situation better, use those knowledge in future events

But try to stay in the present because you can only analyze past not undoing(CTRL+Z) it..
