I have been doing some research on mental prepardness and one thing that I commomly read is that many people about 25 to 30% get off the trail at Neels gap? and when asked why, the typical answer is that "it wasent what they expected." My question is what exactly were they expecting? and how was it different? I am just a little suprised at the answer. And a little baffled at their quitting after 30 miles when they really set out to walk 2000? I am just wondering and trying to envision what others mindsets are as to why they think something is so vastly different than what I would expect when I set out on something if this magnitude.
