As a Ph. D. you tend to get a lot of advice thrown at you about what to do to get an academic job - that's been my experience, anyway. One question in particular that comes up time and again are publications: should you step away from the thesis and write an independent article? Would it be okay to take a slice out of your literature review and turn that into something publishable? Can you afford the time away from the library/field/bed at all?
The best advice I've heard has probably been that the thesis has to come first: you worry about getting your hands on the lily before you try to gild it, I guess. The second thing is getting it done in a relatively brief amount of time - three years usually being the holy grail. After that, everything else in moderation - teaching, attending conferences, and getting publications out there - as long as you have ticks in each box, you're on the right track (NOTE: actually experienced people giving proper job advice here)
