There is a story about an FFA live stock show where the older boys engaged in a calf lifting contest. Each boy would, in turn, select and lift off the ground a heavier calf than the previous boy. Once a boy failed he was out of the contest. When there was just one boy left and he was about to be awarded the prize one of the younger, smaller boys that had been watching called out "Wait, I can beat that!" The other boys laughed at him, told him to be quiet and ruffled his hair. Undaunted, he walked over to his entry in the stock show, a nearly mature bull that weighed fully three times what the heaviest calf lifted weighed. He proceeded to lift that bull three inches off the ground and immediately was greeted with "Ooohs!", "Ahhhhs!", applause and the prize.
When asked how he managed such a feat, the boy explained that, ever since the calf was born, he would lift the calf off the ground once a day. He never missed a day as the animal grew. The boy's calf lifting ability grew into bull lifting ability. To do this he never had to step very far outside his physical comfort zone. Yet by consistently and persistently taking small steps he managed to enlarge his comfort zone to immense proportions.
