I consider it required reading for anyone considering starting a business.

Just want to share this message from his book. (The following are copy from his book.)

The Fatal Assumption is : if you understand the technical part of the business, you understand a business that does technical work.

And the reason it's fatal is that it just isn't true.
In fact, it's the root cause of most small business failures!
The technical work of a business and a business that does work are two totally different things!

To the technician suffering from an Entrepreneurial Seizure, a business is not a business but a place to go to work.

So the carpenter, or the electrician, or the plumber becomes a contractor.
The barber opens up a barbershop.
The technical writer starts a technical writing business.
The hairdresser starts a beauty solon.
The engineer goes into the semicondutor business.
The misician opens up a music store.

All of them believe that by understanding the technical work of the business they are immediately and eminently qualified to run a business that does that kind of work.

And it's simply not true!
