So... why not make it happen? Perhaps not all of it can be done, but Tim Ferriss talks about having an outsourced personal assistant.
If you are the type who could work all those extra hours, try outsourcing as many activities as possible. Start with housekeeping services, as an example, and perhaps a personal cook.
Sometimes I wonder what kind of difference that would make in my life, particularly when I was in grad school.
And then I tell myself to shut up and get back to work.
