We have the same saying and teaching in Buddhism. The concept is called 'sun-doth' meaning to be satisfy (content) with what one has or knowing 'enough is enough'. That's why most people, in my country, in the past were not very ambitious or greedy. But the ideas of progress,capitalism, material gratifications and profit making have changed all that.
