I empathize with how hard it is for a female founder in particular and for a woman in general when it comes to mixing children with a career. That said the advice to freeze your eggs (ie work now, live later) rubs me the wrong way. I wish we could live in a society where people would not have to work themselves to death and were able to... you know... enjoy life
Our society doesn't force or even encourage people to be startup founders -- they choose it for themselves. There are plenty of examples of classes of people who have to work harder than they should in an ideal society, but I'm not sure what point you're making with this particular one.
To many start-ups seem like a short cut - even if they are laughably not.
