Don't procrastinate
For the sand is running swiftly through the hourglass
For every idle word
For every idle thought
Is time that will never be resumed
The sand is chasing
Running speedily, Slipping hastefully  
And there is more sand at the bottom of the hourglass than at the top
Make haste
Do what you have to do, and do it well
No second chances
Until all the sand has run through
And the value of your sand of life shall be weighed up
Don't be slow at doing good
Don't say tomorrow
For we only have today
