What are you going to study in grad school?
Do you hate your job because of the specific tasks you need to perform, or is it more the idea behind what you are doing (i.e., nobody reads it anyway and it's at grade school level; not an effective use of your training to be a writer)?
When I feel unmotivated to do the excruciatingly boring parts of my job (grading papers often comes to mind), I set mini-goals for myself and reward myself afterward. I also find that procrastinating until the very last minute creates enough tension to keep things interesting. :) With that extra fire under my butt, I am amazingly efficient.
If you are at the end of your procrastination rope and are inundated with projects, that may be also leading to lack of interest in your job, 'cause it's overwhelming right now.
Can you organize each project into stacks (or folders, if they are online) and stack the most pressing one on top and just start muscling through (with lots of treats standing by for each time you complete one)? That's what I try to do with my ocean of work (which you will note I am not doing right now). If the most pressing project is too overwhelming, I sometimes start with the easiest ones in order to just get some feeling of accomplishment going (checking things off the checklist feels good).
This is good stuff for me to keep in mind when I go back to work or school, and even now on a daily basis. I really suck at breaking things down. I'm not great at motivating myself.
