The 40 hour business success is the rarity and often it's predicated upon other previous sacrifices made so that 40 hours is later sufficient. As with the xkcd comic, it seems silly to base your success model on the lottery type system that is the rarity rather than on what works most generally. Besides, it's not always about the amount of time being worked. Merit is a combination of hours put in, intelligence, the value of decisions made, etc. I'm not arguing for strictly the number of hours worked. I'm arguing for merit based upon a number of factors vs the idea that all success is determined by luck.
