Practice makes perfect. But we donot need perfection.We need to be consistent. Actually practice makes improvement. The goal is to be better today than we were yesterday and to be better tommorrow than we were today.
The world's youngest man to receive noble prize Late Martin Luther King Jr. famous quote should be kept always in mind while doing your job, which is really a thought to be thought by everyone.
"If a man is called to be a street sweeper, he should sweep streets even as Shakespeare wrote poetry or Beethoven composed music or Tendulkar hit century. He should sweep streets so well that all the hosts of heaven and earth will pause and say, 'Here lived a great streetsweeper who did his job well.'"
Strive always for excellence, not perfection and always try to better your best.
