“A robust and enthusiastic man asks for a job as a woodcutter in a large forest and after an interview with the supervisor, he gets the job. He is assigned a section of trees and they give him the material to start working. The supervisor indicates that he will return in a few days to see how he is progressing. Our man starts the first day with great enthusiasm and by the end of the day he had cut down 15 trees. On the second day, not satisfied with the result of the first day, he decides to work harder and ends up knocking down 12 trees. Surprised, he goes to bed early and on the third day he gets up earlier ready to beat his mark, but he only manages to cut down 8 trees… On the fourth day he gets up before dawn, he does not stop, he works more hours and can only handle 6 trees. Exhausted and disappointed, he sees the supervisor arrive and tells him about his experience. At the end the veteran boss asks him, “In these days how much have you dedicated to sharpening your axe?”
