Aren't entrepreneurs already a class of outliers? I'd be interested to see if there's any research on productivity and how it's related to self-reported relationship with ones work or product and occupation. Probably the most proximate and salient example for me is mathematicians. A lot of them seem to have an almost monkish devotion to math, and breaking their brain day in and day out with little reprieve doesn't seem to bother them at all. Although entrepreneurs are probably not nearly so eclectic, I don't think it's strange to think they might be somewhat exceptional in this regard.
