But there are a ton of people doing it. Check out this quote from the business section of the Kansas City Star:
The U.S. Census Bureau last fall reported an almost unbelievable number: Self-employed individuals who have no paid employees operate three-fourths of U.S. businesses. These self-employed roamers may miss co-worker camaraderie, but, boy, do some office-bound employees covet their peripatetic “bedouin” style.
Everyone of those people is contributing something, and probably everyone of them thinks, "why don't I have a normal job?" But the entrepreneur is becoming the new normal.
