WorkWe cannot live by nature alone. We have to modify the nature to satisfy our diversified wants. As we cannot modify and innovate the nature all by oneself for his life alone, there is division of putting in efforts. And this effort put in a systematic manner is called as work. When we require a product developed using someone else's work, is known as demand. As normally all the work carries a cost, the efforts are priced in terms of money. |
