Nice article by Rob Fitzpatrick (founder of London-based, YC-funded Habit Industries), using the analogy of a coffee shop to hammer home the concept that wanting to work in your startup is not a good reason to start a startup. It's a good read, enjoy.
This is a familiar point for readers of E-myth, and it applies to startups as much as to other businesses. Being a founder is not so much about building products or making sales as it is about building a business. In order to do this effectively, you need to be able to mentally step out of the day job of working in the company, and working instead on the company.
