To-morrow — oh, ’twill never be,
If we should live a thousand years!
Our time is all to-day, to-day,
The same, though changed; and while it flies
With still small voice the moments say:
“To-day, to-day, be wise, be wise.”
~James Montgomery, To-day

Therefore do not worry about tomorrow, for tomorrow will worry about itself. Each day has enough trouble of its own. Matthew 6:34
