The Y Axis (Or Y Not)

They say its all downhill
From here
.............. Or here
........................... Or here
But I can recall no hills
I've been crawling on my belly
Slithering like a snake
Coiling around finger holds
Because this is all strictly vertical
As if the only way up is, well, up
One foot after the other
This hand then that
And I'm back again, creeping
Over this so called mountain
The horizon is not clear
Because I do not dare
To take it all in and enjoy the view
I mean, have you ever tried clinging to a wall?
