The past is gone

The past is past and gone;
Why cling to it?
Or why worry about what is gone?
Never will you have it again;
The present is there for you;
Why not make the most of it?
Even the future is still to come;
And none can say if it will;
No need to worry at all;
The future none can tell;
What you have is now;
Leave the past
And leave the future
To take care of themselves;
Make the most of now.
