A mesa is a high table land, a plateau on top of a mountain. This is where a lot of people stop, they've achieved, tasted success then turn statuesque. Unable to progress or move from this they either stagnate or fall down those cliffs to begin again. Failure isn't something to be afraid of, indeed it's a place for the greatest learnings.
But what if there was another way. You've got some rocks. You've got some fuel. Dead leaves, dried shrubs, a few lizard brains. Bang those rocks together, light those brains on fire and see what happens. Now ask … is this self immolation or do I use the heat to climb higher?
