Marissa Mayer, the CEO of Yahoo, is not the primary caregiver for her small children; she has nannies on staff and administrators to handle her personal life so that she can enjoy the time she has with her children. Good for her; she’s living her life as she sees fit. But don’t pretend that if you can’t hire a nanny and a personal assistant and you are the primary caregiver for small children that you can have Marissa Mayer’s life and be in an early-stage startup.
