His boss gave him an axe and showed him the area where he was supposed to work.
The first day, the woodcutter brought 18 trees
"Congratulations," the boss said. "Go on that way!"
Very motivated for the boss’ words, the woodcutter try harder the next day, but he only could bring 15 trees. The third day he try even harder, but he only could bring 10 trees. Day after day he was bringing less and less trees.
