A lot of time in a PhD program is spent reading articles, which still gives you a pretty flexible schedule even though you end up spending _a lot_ of time reading them.
Sounds like my life. I've been furiously trying to publish recently--leaving for a conference to present a paper within a week, in fact--in an attempt to lift myself above the bottom rung of academia. Articles? Articles? They're my life recently--oh, that along with teaching, of course. I'm so obsessed I'm dreamin' about the things--no, nightmares, actually.
