Sharpen your Axe

Jo John, a woodcutter, worked  for a company for five years but never got a raise. The company hired Bill and within a year he got a raise. This caused resentment in John and he went  to his boss to talk about it. The boss said, "You are still cutting the same number of trees you were cutting five years ago. We are a result-oriented company and would be happy to give you a raise if your productivity goes up." John went back, started hitting  harder and putting in longer hours but he still wasn't able to cut more trees. He went back to his boss and told him his dilemma. The boss told John to go talk to Bill. "Maybe  there is something Bill knows that you and l don't." John asked Bill how he managed to cut more trees. Bill answered, "After every tree l cut, l take a break for two minutes and sharpen my axe. When was
the last time you sharpened your axe?" This question hit home like a bullet and John got his answer.

My question is,  when was the last time you sharpened your axe?
          
        Past glory and education don't do it. We have to continuously sharpen the axe.
