I believe there *are* companies out there where you can make it the main focus of your life, working for them, and actually have some justification for doing so.
In the current tech sector, there are really only a few that come to mind. I'd say Google would be one. Apple would be another. Facebook tries to be yet another, but I have mixed feelings on whether or not they've really "arrived" in that way.
I'm talking about companies that have earned a lot of respect for continuously doing things that make people's lives better. There are so many of us who go through life lacking "purpose". People get up every day and go to a job, just because that's what you're "supposed to do", come home and do a lot of little, relatively pointless stuff, pay the required bills... rinse and repeat.
Whether male or female, I can understand why some people would find that sense of purpose in working for one of these companies that's actually changing the course of society's future. (I mean, if you're talking about communication tools alone -- look how different things are today with the advent of the smartphone. Look how much easy access we have to music thanks to the digital music revolution. Look at what cellular data connected tablet devices allow people to do.) You can say what you will about Apple, Google, or even Intel or Microsoft ... but working on the right projects for one of them HAS to be more rewarding than working as a gas station attendant, a retail sales person at a clothing store, or any number of other misc. jobs out there.
So yeah... it's not for everyone, but I get why *some* people would actually want the work/life balance tipped heavily towards their work. It's just not something you want to feel is FORCED upon you, and probably not healthy at all if your job isn't one of the real "movers and shakers" that actually accomplishes major things.
