Business is an economic system in which goods and services are exchanged for one another or money, on the basis of their perceived worth. Every business requires some form of investment and a sufficient number of customers to whom its output can be sold at profit on a consistent basis.
Business is basically something where you do and gain maximum profit. If in long term, you are gaining profit then you have a successful business and if in long term you are suffering a huge amount of loss then your business is not successful.
