The black dog

You do not live in the past. 
You learn from it. 
You yearn for a future 
For which there's no certainty 
Now live in the moment 
And live every breath

What could have been 
Wasn't 
What you long for tomorrow 
Today controls 
So live for today 
Live in control

Set yourself goals 
And start to climb out 
Achieve today 
And change tomorrow 
Runaway black dog 
Run along now
