The next month he put in the same effort but could cut only 15 trees. And the third month, he still tried his best but could cut only 12 trees. The king visited him the third month and talked about his decrease in productivity.
He explained that he might have lost his strength or got too old to do the work. The king asked him “when was the last time you sharpened your ax?” To the surprise, he has not even done it once in the last three months. That was the only reason why he couldn’t cut more trees.
Moral: It is good that you put in a lot of effort and hard work to work towards your goals. But you should balance your life priorities and invest time with your family and save some time to relax which would boost up your productivity.
