I do it by priorities. The closer a deadline in addition to most work involved, the more emphasis it gets. Essentially, if there is a fire under my ass, many pretensions for laziness or procrastination go out the window. It is during moments of relative luxury that procrastination seeps in my brain.
By the end of this weekend and into the early part of next week I need to have started and finished two books (one book for monday, another for wed.), in another class finish one text and begin another (exam next friday), write two essays, conduct a lengthy examination of a particular historical journal from inception to now, examine local/state records during office hours, grade in-class essays for a large 100 level course, and begin contacting certain people for future research. By the end of the week I also have an examination in the class I have to finish/begin those two books.
It all comes down to setting time limits hour by hour, and giving myself manufactured sanity breaks (something like a generous half hour). So far I have enforced a "cool down" period late at night to relax, perhaps enjoy a television program or something before going to bed. I never used to do this as I was always so anxious to finish everything, or understand the essence of what I was researching, that I wore myself down.
So tonight, I started by looking over portions of those state/local records before they closed, I will finish a text for tomorrow, and begin doing most of my work on the historical journal. Then tomorrow when I receive those essays to grade, I will have to first go over more state/local records until they close, get back to the apartment, and grade some number of essays, stop and eat/break, go to background information on one book I have to read & then start gutting it apart...go to bed. I have up until Saturday night planned, and will figure out what to do on Sunday when it comes to essay grading, how far I get in Text A that has to be read and responded to in essay form, and which sections of Text B I absolutely need to hit before Tuesday. Monday will be some mixture of grading, reading Text B, and writing up a thing for the local/state history documents. Tuesday will be final preparation for the state/local history documents in addition to priority reading & test prep for Friday.
And so it goes.
