Accuracy in placing a line high in a tree might be easy but pulling up into the tree could present a difficult task. Dealing with the unexpected. Sudden unforeseen events can make one scramble. Getting too close to a creature's nest could bring out the wrath of a protective parent. One must be creative to solve problems.
Few climbs are straight to the top without route changes and detours.
One can not expect standing above others in excellence without taking risks. The highest branch might not support one's weight. Cooperation with others. Climbing alone is dangerous. The person who ties on the tools to be used aloft saves the climber from fatigue by not having to climb up and down.
