An Effort

It's time to make an effort, push a bit
Against your destiny, towards the past.
The alteration hasn't been so vast
That you can't just go back. Calm down, and sit
Beside your old friends, where the lamps are lit,
And prise yourself from darkness. Now, at last,
The daylight's gone. You thought the die was cast,
But yesterday is coming. Wait for it.

Now you'll attach yourself to yesterday,
Which has some clear advantages for you:
You'll seem much smarter, though you have no clue
About tomorrow; when you want to play,
No one will blame you; watch for some delay,
But overall, you'll like the tried and true.
