Yeah - no worries. Except for E-myth Manganager - I didn't either until a couple of years ago my younger brother was going to open up a clinic and was talking about "E-myth for Doctors" or some such. Now I think he has one for all walks of life (like the "One minute Manager" or something). To me, it dilutes the message. My opinion is not the one that counts! :-)
I suspect it is this one based on the summary at Amazon "Michael Gerber's The E-Myth Revisited should be required listening for anyone thinking about starting a business or for those who have already taken that fateful step. The title refers to the author's belief that entrepreneurs--typically brimming with good but distracting ideas--make poor businesspeople."
