I once submitted a local hill over 50 times through the course of a year, each ascension was marked with the collection of a small pebble. On the final ascension of climb number 51 the stones were returned to make a tiny cairn. it why 51? well that is the actual height of Everest from sea level, all completed without oxygen and mainly with my dog. A tall task is only as big as the parts and the time allocated. What is your monster.
