Stairway to heaven

The stairway to heaven
Is long, steep, narrow, and hard.
Push through it with all your might,
And you might set flight.
To fly from this mess.
It puts you to the test
Ya gotta do your best
On this stairway to heaven,
there's no mistakes allowed.
This stairway to heaven,
is allowed only to the best.
So try you're hardest,
and you might pass the test.
