Ignoring even Penelope Trunk's tendency to extrapolate from her experiences to the rest of the female world, the conclusion she's drawing doesn't actually follow from her own experiences. She says she's taking time away from her third startup to spend time with her children. Therefore women don't do startups because they want to have time with their children. What now? Wouldn't that suggest rather that women who want to do startups can do so and then have time for children afterwards?
