By the advance of internet, the number of the people, called SOHO(Small Office Home Office) race, who work at a house, not at an office, and do for living are gradually being increased. It is a natural result by the advance of computer and way of communication. But we need to know exactly profit and loss gained by working at home. First of all, regarding the profit of a work at home, we can say a freedom, convenience, and financial saving, etc. What we can work without any interferences, limits of time, financial consumption of transportation and food charge, etc.. will be big merits. But we can not ignore the demerits in accordance with it. Convenience and feedom gained by working at home is apt to be changed to self-indulgence.If they feel the convenience and feedom, as human being is wicked existence, they would want more than it. Therefore, they will need bigger will than the workers of an office to control and govern themselves in order to be the SOHO race.
