It's okay, it's okay, it's okay.
Just keep saying it.
It is OKAY.

The world will not end,
and you probably won't fail anyway.

Even if you did, there is always a backup plan.

Barring a backup plan, the world will keep spinning.

and...

in the catastrophically unlikely event that
our little planet stops going 'round,

you will no longer be.

That's a comforting thought, really.

That if anything were that bad, we wouldn't have to endure it.
