I think the problem is, the work (on computers) is never done. It takes months for me to say, "well, I got that wheat harvested" (in computer terms). There's always some more bullshit, so you can't just step away; more is always waiting, and you're always blocking someone somehow.
The way we make money digitally does not map to a practical, dynamic life. We need to re-structure what "work" is, what it is we are trying to accomplish, and how.
