"Ignore the ramblings of the ignorant, and step on or over their crumpled bodies as you make your way to the top of the mountain. Eat upon their flesh for fuel, and, through your determination and will, banish them to obscurity and a life of complacency and self righteousness that is the hell in which they live"
-Richard Safreed
