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
