Fred Wilson is one of my favorite bloggers, and he listed his answers to “10 Questions About Entrepreneurship” – including referring to it as a personality disorder, and questioning whether or not entrepreneurs are happier than “regular” folks.
For one, it may not be a disorder (because that carries a certain negative connotation) but it definitely is a personality aberration. I mean, who would consider high-level OCD coupled with ADHD, severe insomnia, extreme excitability, and mood swings a “disorder”……oh, wait…All those traits could also be referred to as passion, drive, ambition, and a quest to make the world a better place and achieve self-fulfillment. It just depends on whether or not you’re trying to sell medication 
As to whether or not we’re happier – I think our mood swings take us higher (it’s the self fulfillment thing), and the lows don’t take us quite as low, since a successful entrepreneur learns at a very earl age to embrace a challenge as opposed to let it keep them down too long. Now, that is completely achievable outside of our little sphere of crazy people, but I think it affects entrepreneurs at a much higher rate than your cubicle warrior. Hence, I would suggest entrepreneurs are, on average, slightly happier.
He also talks a bit about how Indeed is making job searching more intelligent. This sounds kind of like some stuff we’re working on with HHOD. I wonder if Fred would be interesting in hearing about that?
*crickets*
And, yes, I know that these posts are a bit older, but I only get to my aggregator about once a week these days. I’ve been too busy running around and talking about HHOD to schools and finding out exactly how cool our idea is.
