Practical question

Hey guys. I'm wondering what, in a perfect world, your preferred day of reading is like, what the ratio of primary literature to theory to non-theoretical criticism would be. I'm reading kind of a lot of critical writing at the moment — an occupational hazard if you're writing a thesis on poet-critics, I guess — and I'm a bit worried about getting burnt out. I feel as though the argument-assessment part of my brain is getting hypertrophied while the aesthetic-assessment part starts to wither.

Anyway, thoughts welcome.
