An enterprising entrepreneur may choose to build their business by boot-strapping, rather than by trying to find some other source of funding. Some advantages of boot-strapping are that the entrepreneur retains control of their business and that the business is much less vulnerable in an economic downturn, when other businesses may be going under.
Also, a business built this way may be more solid, because it is built step-by-step, each piece locking in to the other business components. Any mistakes, or need for adjustments, can be dealt with while the business is still at a low level, before it has gone national with its problems. Business practices can be fine-tuned on the way up.
The most interesting part of building a business by boot-strapping, though, is how much fun it is! Business analysts can watch a business like that - tweak it with their comments, concerns, and well-meant advice - and feel, as others do, that everyone has a part in this business.

Certainly, most businesses are more than any one person could build by themselves.
