I asked this question to Rajesh a project manager in an IT company, during one of my coaching session last year.

He replied: what do you mean??
Let me tell you a story: Once the Owner of a big furniture company, hired a young dynamic wood cutter to cut trees to be used for creating beautiful furniture.
Day 1 @ Job: the wood cutter worked with a lots of excitement and energy and could cut 18 trees by the end of the day. He reported to his boss and got pat in the back. He promised his boss to perform better the next day.
Day: 2 @ Job: The wood cutter got 20 trees down with his hard work.
Day: 3 @ Job: The count of trees came down to 14.
Day: 4, 5 & 6 @ Job: The count of trees went drastically down to 12, 8 & 6 respectively.

Day: 7 @ Job: The frustrated wood cutter could get only 4trees down. And on his way back, his fear, frustration and failure had pushed him to decide to step down from his job and intimate his boss.

He returned to the factory and reached his boss and told the story of past 7days. And expressed to accept his resignation from the job.

His boss asked with a smile, dear – when was the last time you sharpened your AXE ?
Learning notes:
Continual sharpening of your axe (knowledge / skills / attitude) would help you cut more trees.
