On a more serious note, my Philosophy *not my major* professor talked of a story of a man following some monks up a mountain to their temple. And the man looked up at the mountain and thought it would kick his ass. And all the time he was looking up, seeing how much further it was until he reached the top. And after awhile, other monks started passing him, all the while looking down.
They were looking down and just trucking along, and when they got to the top, it was a simply running out of mountain to climb, it wasn't looked at as a feat.
I don't know about you guys, but I've always looked down - with brief checks up to look for obstacles, glass, morons, etc - when climbing hills. It's a huge pyschological abvantage to be just gutting it out rather than thinking "Man, when will this hill just stop?". It's sort of like running in the Marine Corps in the US, just lean forward and stop yourself from falling until it's over.
