In his blog, Pablo Brenner lists Rules for Revolutionaries by Guy Kawasaki as one of his favorite books. The book' s subtitle is "Create like a god, command like a king, work as a slave".
I guess you can characterise the successful entrepreneur as someone that creates like a god, commands like a king and works as a slave. As someone who studied psychology for many years, Pablo should know that you can diagnose this kind of person as something else: a schyzofrenic. Wikipedia tells us that one of the main characterizations of schyzofrenia is significant social or occupational dysfuntion.
Let's be realistic: if you can command like a king and create like a god, you have to be out of your mind to work as a slave. Not that there aren't many of these, I see them every day. The worst part of it is that many entrepreneurs that I know, enjoy most the slave part.
So here is a niche market: a psychological clinic for entrepreneurs. Convince them to drop one of the three. Or maybe two. They could start by enjoying a bit of Second Life. But they could do much better: get a First Life.
Here is a challenge for you Pablo: how would you characterize the Venture Capitalist?
