As a lone entrepreneur in a city that is very un-entrepreneurial (even anti-entrepreneurial in some ways), I think this is a good idea assuming you invite the right people to the launch party.  You need people who will celebrate your risk-taking adventure with you as well as be there in a positive way when things get very hard or if it ultimately fails.<p>Although I know the title is denigrating, it actually is good advice.  My first effort failed miserably, causing me to slink back to a nine-to-fiver I hate.  Once I came to terms with why I had failed the first time and shared those deeply personal things with others, I find my second time around is much clearer and focused.  And those who are informed and care help to remind me of what not to do as much as what to do.  In some ways, they are like silent co-founders.
