I totally agree with you. And although my two sons are too young to accurately observe this on them, I can tell you I fit the bill. I can manage on the 'fixed path', working in a company that has a plan sorted out, but I feel constrained and frustrated. I see rules as something nice but that has to be allowed to be broken when its the right thing to do. So I did do my start up journeys. A few times over the last 20 years and I'm still at it. I have never, however, heard it explained in that manner as to WHY I feel most comfortable when the odds are stacked against me and when I'm doomed and expected to fail. I revel in those moment as i know its my time to spark up and deliver. And when things get routine my light seem to dim... Until the next 'crisis'.
