Who is there among us who hasn’t dreamed of having his or her own small (maybe , several years later , even big )business , and having wonderful freedom , both from a boss and from the time clock ; the freedom to make up our own rules for our work , and our own plans —arranging our own hours of work ? That way work would be both painless and fun. Or, so we imagine.

Well, in fact it isn’t quite as simple as that. Yes , it is true that being the boss has its satisfactions and that you can arrange your working hours freely if you own your own small business . But in those early years of starting your own business, you shouldn’t think of a free day, not to mention flying off for a month’s vacation. It is not unusual for new business owners to work seventy or eighty hours a week , and if there is a day off , that day might need to be devoted to accounting (算账).

But this negative picture doesn’t destroy the beautiful hopes. The possibility of getting something wonderful in return—both material and mental—continues to drive that large number of people who start up small businesses each year in the United States.
