I can understand how such a blanket statement can be infuriating but i recommend taking it with a pinch of salt…I am certain Marissa was referring to it as an indication of likely success…that presence on a saturday is an indicator (not absolute) of work ethic and therefore with supreme hard work being a relative prerequisite for start up success…a start up whose individuals display this work ethic have i imagine a statistically better shot at success.

Shes a smart women…its not arrogance, it opinion based on her experience i imagine.
