Why people go in past

Why people go in past,
Since they doesn't understand 
The value of present or
They live the past or 
They don't want to live in the present,
Therefore, they always talk about their past.

What is good to live in present, past or future,

Although, no one can go in 

The past or future physically,

Only they can only talk about their memory,

They love history, they love to discuss histry,

No one like to talk about the present.

You can only learn a lesson from your past,

But you can't carry the burden of 

Your past on your shoulders,

You may plan about the future,

By using the present,

But not to worry about the future,

We should to focus on our present and

We should to live every moment of life fully.

Thank You.
