Two lumberjacks worked in the same forest to cut the trees down.
The trunks were majestic, strong and firm.
The two lumberjacks used their axes with the same cleverness, but with a different process: the first hit his tree with incredible perseverance, a blow after the other, just stopping to breathe again for rare seconds.
The second lumberjack did a moderate break every hour of work.
At dusk, the first woodcutter's tree was half-finished.
He sweated blood and tears and wouldn't have stand for other five minutes.
The second was unbelievably at the end of his tree.
They started together and the two trees were identical!
The first lumberjack didn't believe one's own eyes.
"I understand nothing!
How did you do to finish so fastly if you stopped every hour?".
The other smiled: "You saw who I stopped every hour, but what you didn't see is that I took advantage of the break sharpening my axe".
